General Bug Fixing

Hello everyone! Small update today.

-A few fights are no longer broken. Chingus no longer is immune to every damage type, Diana's ramping up Aggro system was removed and now she just acts literally every other action, and Akari no longer has a damage formula that divides by zero and crashes the game.
-Balance adjustments; several fights had their Aggro values altered slightly and stats adjusted to help them stand out a bit differently.
-Going back to previous world maps no longer gets you stuck in places (there were some changes to maps late in development and the transfer points were never changed, but they are now).

I'm still reviewing the game's overall balance, so please feel free to comment here or elsewhere to me about any fights you feel are too easy/hard for their place in the game, or if you have any bug reports.

Thank you all for playing!
