v1.2 - now with more stuff

Maneuver Ability is now feature complete. It only took almost a year, but it now includes everything I'd originally wanted to include in the game but had to drop from the 7DRL version in the interest of getting it done in a week.

Major changes:

• Significantly more enemy types, there's now one for each letter of the alphabet plus one extra thing
• Various tweaks to balance, most notably buffing mushrooms to be less harmless
• Game now has a victory condition, though is possibly still a bit too difficult
• Major performance improvements

This will probably be the final update. I don't really have anything else I strongly care about adding and I will be doing the 7DRL challenge again this year, so expanding that will probably keep me busy for a while.
