SC3k-style Ordinances

This wound up being a bigger commit than I had initially planned.

- New SC3k-style policies based on the advisor code.
- Added license file to Font Awesome folder.
- Refactored the advisor code so it can handle multiple files.
- Updated icons. Should be more consistent now.
- Replaced Sims with Animals in ticker text.
- Moved dialogs to windows directory.
