Quiet annoying warning:

  Warning! Tesselation uvs or vcol data got out of sync, "had to reset!

This would happen on every editmode edit with UV's and wasn't too reassuring that blender was handling uvs/vcols correctly.

From looking into the problem I found that creating the undo mesh would act as if it was tessellating the existing mesh each time and complain that the data was out of sync, when infact the mesh was just created and being filled in.

Also, allocating uv and vcol customdata arrats for tessfaces isn't needed for undo mesh, so save some memory and dont allocate these in the first place.
