Blendshape export float & same # verts 

Previously it was possible that the number of vertices between the mesh and morph mesh varied.
This may have caused problems in tools like Blender, and this ensures there's a 1-1
correspondence between vertices.

In addition, exporting doubles broke meshlab on import, so now it exports floats.
