Fixed gray texture on export.

Browse Source 
Fixed gray texture on export bug, it was caused by the texture scale function (during upscaling), right now it's required to have the texture dimensions be a power of 2 width/height.
Optional OBJ/PNG/sprite export options.
Chanaged readme.
TODO: Cleanup export code. Make proper scale options (bilinear & point).
