- added mesh_get_texspace (should be used instead of direct access)

which calculates texspace on demand if need be.
 - removed almost all calls to tex_space_mesh

There may be a few corner cases where this goes wrong (meshes with vertex
keys) but these should get ironed out by coming modifier system.
