Added a small Paint Department, as any Home Depot should have.
And made sure it wasn't busted by A17.4
Added in v1.3:
Restored access to a couple of textures that were included with the paint brush but hidden (Orange Drywall & Tar Paper).
Also, found a few textures that work decently enough on blocks and included them (Bookcase, Vent, WashingMachine, & Wet Concrete).
