Ripped out SQLite

I spent 2 days ripping out SQLite. I love having a light SQL database to work with - it definitely helped me prototype some design quickly. However, dealing with saving/loading the .db across different platforms was giving me issues, and so I am switching to just using Godot's built-in custom resources feature. It's been going well, and it helped me clean up my code.

I did have to basically re-write all of the functions in my game, and based on some of my recent work on Camp Check, I made some design changes, too.

TLDR: an optimization patch
