Various Fixes and Upgrades

Rebased upon v1.12 and cherry-picked commits from August 18th and 19th, before MasaYume merged in anpc.py and started to completely change the entire game, which largely removed a lot of my code.

v1.12

• Removed remnants of logic gate in main menu
• Use Pickle to save the Player object, loading the saved object doesn't work yet
• Increased the health of the Dragon mid-boss

v1.11

• Fixed the save game feature (just saves one property)
