Music Score and JSON files WIP

- WIP music score inspired by The Sims 2's CAS. This is what Tony's Dress Up was inspired by back when it was still a Flash project.
- WIP JSON support for parsing clothings and rendering clothing as buttons
- Extended gitignore to support all of .NET Core and Monodevelop, due to Godot's upcoming support of the latter and future-proofing the former with .NET 5 inbound.
