needs AI branch
- Refactored code again, made Item.java an inner class of ItemSet.java
- Everything is now generic. To add an item:
	add it to the enum list
	define it in the itemSet.java constructor
- Items now support multiple stats
	ex. Coffee now gives   -> +5 Hunger and +30 Energy
- Removed "eat" command. "use" command now handles food by destroying if item is consumable

- fixed .gitignore, now ignores eclipse metadata
