Made it so blender has an active render layer for Uv and Vertex color mesh layers.

This means changing the active UV/VCol layers wont change what renders.
needed to adjust the minor version so old files will copy the active layer to the render-uv/vcol layer.

boxpack2d.py - redoen in C now, dont need python version.
