Major clean up and reorganization

- Upgraded to Godot 4
- Just remembered the basic principles are based on a tile editor, and dramatically simplified from there. Derp.
- New state machine and license display add-ons.
- Re-licensed under the GPL because Micropolis' assets aren't under a separate one.

+Creative Commons Legal Code
+
+CC0 1.0 Universal
+
+	CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+	LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+	ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+	INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+	REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
+	PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+	THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+	HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+	 communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+	 likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+	 subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+	 in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+	 European Parliament and of the Council of 11 March 1996 on the legal
+	 protection of databases, and under any national implementation
+	 thereof, including any amended or successor version of such
+	 directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+	 world based on applicable law or treaty, and any national
+	 implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+	surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+	warranties of any kind concerning the Work, express, implied,
+	statutory or otherwise, including without limitation warranties of
+	title, merchantability, fitness for a particular purpose, non
+	infringement, or the absence of latent or other defects, accuracy, or
+	the present or absence of errors, whether or not discoverable, all to
+	the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+	that may apply to the Work or any use thereof, including without
+	limitation any person's Copyright and Related Rights in the Work.
+	Further, Affirmer disclaims responsibility for obtaining any necessary
+	consents, permissions or other rights required for any use of the
+	Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+	party to this document and has no duty or obligation with respect to
+	this CC0 or use of the Work.

+A simple plugin, to make dealing with licensing simple.
+Files: ./addons/simplelicense/*
+License: CC0-1.0
+
+Developed in Godot version: v4.0.beta.custom_build [166df0896]
+
+Quick Example: (A License Viewer Scene, that you can also drop into one of your game scenes)
+	Run the Scene at
+	res://addons/simplelicense/GUI/LicenseGUI.tscn
+	
+	look around, then
+	click on the "open data directory" button
+	then click on the "save licenses" button
+	and watch the data directory populate with license files
+
+
+Quick Start:
+	1. Create a "LicenseLink" Resource file inside the
+		res://licenses/license_links/
+
+	2. Click on the the new Resource file, and try it out
+		There are docs on how to use it, so just F1 + LicenseLink, to find out more
+
+	3. Load license information
+		Create an instance of "LicenseManager" either in code or by adding the node to the scene
+		then call "load_license_information" on the LicenseManager
+
+	4. Export License information
+		call "export" function on the LicenseManager
+		it will populate the "user://" directory with your license files
+		one combined "COPYRIGHT.txt" file
+		and individual copyright files into "user://licenses/<license_identifier>.txt".
+		The license text will be formatted in the SPDX standard.
+		It's the way the Godot Engine does it.
+		 in the Godot Editor: Help -> About Godot -> Third-party Licenses
+		There is more you can do, just visit the docs!
+		(Like support for loading mod's license information!)
