added item image files
adding lots of graphics and item stuff...

- organized the resources folder
- added an item_set surface for items (32x32 pixel sprites)
- refined items.h
- functions added:
	- set_pixel()		// these two are going to be
	- get_pixel()		// very VERY useful
	- apply_text()
	- apply_surface_clips()
- condensed the debugging information by using apply_text() instead of doing it manually everytime.
- cleaned up main()
