v1.2 Evolution Update

Huge changes to the game. A lot of stuff have been reworked and polished.

• new era with 3 new bosses and evolutions,
• 8 new skills (18 including evolutions),
• changes to game balance, ui, sprites and a lot of other things.

The game is pretty finished now and I probably wont do any more updates to it, unless some smaller bug fixes or changes.
