- Rough start of the SQLite integration to facilitate the SQL queries - Cleanup and disable a little bit of code so the game no longer crashes when entering the editor - Implement some of the mouse data stuff  https://user-images.githubusercontent.com/13153231/202881484-399747e7-dcdb-4e09-93e9-b561a45c8a18.mp4 This is a very old branch so best to get it merged now that it's at a decent point so it can be iterated on.
