Change Parched texture and allow them to spawn in Badlands

First of all; Parched should spawn in Badlands as the hostile mob variety there is quite stale, but before they can add that; they have to change Parched texture to fit both in Deserts and Badlands.

These are the changes they should make to Parched's texture:

• Give them empty/black eyes. There's too many skeletons with 'glowing' white eyes at the moment, Parched are already unique with the cloth around them.
• Recolor the yellow-ish cloth into something more light brown-ish. This would help them fit well with Badland's more reddish environment while still fitting well in Deserts.
