Alpha 005 - Lots of changes

Started working on the main loop.

You now start with a magic rock. You have to throw it and summon it. Right now I think it's a bit boring to type the same commands again and again so I'm going to have to look into making that a bit more fun. 

Chests and pots now contain money and mana and upgrade spells... Be sure to break them all to look for items.

Enraged creatures are creatures that turn red. They're stronger and faster than their non-enraged counterparts.
