Increased .OBJ model support

Now supports vertex points without decimals and vertex points with powers of 10. 

For example, Cinema 4D uses vertex points without decimals when placed exactly on the ground. Riptide OBJ exporter sometimes uses powers of ten.

Will not affect already working OBJ renders.

UPDATE: Also added support form OBJ files that both have triangle vertices and quad vertices. Most 3D programs should work now with this addition. This, again, does not affect already working .OBJ model renders.
