Blender Export Script

I've revised the Blender Objective-C Export Script. It was a relatively minor change - I was calculating the vertex normals based on the face normals, which was unnecessary work since Blender keeps track of vertex normals as well. On larger models, this version should perform better than the original version since it doesn't have to calculate vertex normals by looping through all vertices on all faces looking for matches.

A bit off topic ...

I ran some basic 2d fill rate tests based on displaying simple alpha-blended 32x32 quads.

Compared to the old iPhone, I was able to display about 5 times more sprites.

This test is part of my small 2d demo and with the old one I was able to display 350 32x32 blended sprites ( in addition to some non-blended and UV animated background images) while maintaining around 30 fps.
With the new one I was able to push the number of quads to 1750.
