Desert Biome

Additions 

Added new tiles for Desert Biome along with some objects for the area.

A simple character sprite with 2 frame walking animations.

Objects for Desert:

Rock

Cactus top and bottom

Bleached Skull

Bleached ribcage

Dead Bush

Notes:

The Desert Biome is not finished Still need to add Cracked soil to blend in to normal soil so it can transition between desert and badlands style area.  Badlands will be the next area added as it shares tiles with desert.
