Title: Flip vertical texture coordinates for .obj import

So far load_obj has treated uv0,0 as top left corner while blender/max understand that as lower left, so a bunch of models have their textures flipped to accommodate this. Better to fix it in the loader instead.

This affects models using load_obj where the .obj has uv coords. A bunch of textures need to be re-flipped after this.
