Added quite a lot of stuff. 

SpriteSheet
-Added parser
-- New file type ~~ .sheet
		xxx.png -> xxx.sheet 
		Spritesheet will be automatically made from values contained within.
		Example can be found under res/hydrogenhank/HydrogenHankSpriteSheet
		
		The .sheet files are to be located in the same directory as their
		spritesheet counter parts
		
-Parameters are now String, spriteID
-loadImage is done from within sprite sheet

Added spriteID enum

Updated graphics for Hank

ArtAssets is no longer accessable as a static instance. Now there is a
getter. 

Spritesheets cannot be accessed globally either. Must use getter.
