performance has dropped, unfortunately
Various performance improvements (and GUIText)

-Creature sprites are now saved in their object to reduce memory usage
-GUIText class added to allow text placement without a background
-Flowers increased
Updated .jar
Removed more debug stuff
Added more player images
Removed debug info and renamed some images
Resources now functional
 Added rock resource
Introduced layers
Sprite map now static

-Huge performance improvement
-A function for unloading sprites from the list may need to be added
later
