Blender Git Commit Log

- change mesh_calc_normals to set vertices with len(no)==0
to normalised coordinate (convention in blender, helps with
halo)
- removed vertexnormals(), vertexnormals_mesh()
- removed CTX_NO_NOR_RECALC (always assume already calculated)
- change NMesh.c to call mesh_calc_normals
- chance load_editMesh to call mesh_calc_normals after done
converting instead of using editmesh normals
- update recalc_editnormals to also calc vertex normals (whats
4 more adds and a sqrt among friends)

Its hard to believe, but it just might be the case that there
are only two places mesh normals are calculated now (renderer
and kernel)
