Sprites and more sprites!

I have been delaying this for ages.  I have added carpets, grass, dirt,
and grid turf!  I have added an engraved zippo, a raptor toy, das boot
drink, golden cookie, and a wall clock as items!  I have added blue
skrell as well as more head-tails for skrell fun times!  I have added a
different colored corgi!  I have added a bunneh!  I have added custom,
brand new PDA icons!

Special thanks to all the spriters who have executed these, it's been a
long time coming, but they're uploaded.
