1.2.2.1 multiple savestates source code

[cerpintext]

Allows multiple savestates, not very elegantly, and potential for murdering performance, but haven't managed sufficient testing for that. If it turns out to be a significant problem then rewriting to add a performance mode should be simple enough, if not then these are relatively fast savestates for all states. Unfortunately it forces a new settings file for binds just because renaming things I didn't like.

Otherwise:

• Ported over Hitbox-Viewer as a bindable function
• Added instructions on how to use multiple savestates

Basically requires a new branch or something
