* Lattices: properties editable, editmode operators, menus working
again. As a bonus you can now edit u/v/w in editmode.
* Shape Keys: some code cleanup, and added more buttons. The
value/min/max buttons don't work correct yet though.
* Fix issue with uv textures, vertex colors not being visible outside
editmode, and a few other issue. Mesh.edit_mesh is now NULL when
not in editmode.
- restored three more C files: editlattice, editkey
and editgroup
- editmode lattice working, (mouse select works)
- accidentally removed yesterday 3d cursor drawing
- removed global editLatt entirely now.
