v1.12 in-battle deck edit

v1.12 changes:

• After a match, there's a new button to Edit Deck and then quickly retry.
• Puzzle 2 changed to be more fair... and more puzzle-y!
• EDIT: Animation speedup now works better! It persists between fights, doesn't glitch out, and is reduced from 3x to 1.5x.
• Fixed various glitches that occurred when switching between save files.
• Shortened some boss fights in casual mode (no longer always 20 turns).

v1.12.2

• Added versions of 79, 83, and 97 fight for Casual difficulty (previously 79 and 83 were the same at both difficulties!).
• 97 fight no longer has disconnected islands. Now there's more flexibility in choosing a deck, especially in a 20-Battle challenge run.
