Lots of BPy Mesh additions:

- added faces.uvSel attribute: can get/set selection status of UV vertices in
  UV Editor window
- make mesh.faceUV, mesh.vertexUV and mesh.vertexColor writable: users
  can now enable/disable UV faces, vertex colors, "sticky" vertices
- fixed bug with mesh tool methods: before it would only work if an object
  linked to the mesh was selected
- added mesh.quadToTriangle() and mesh.triangleToQuad() methods
- added selected() method to verts, edges, faces; returns list of indices
  of selected items
- mesh.getFromObject() now gets derived mesh data
- ported vertex group methods from NMesh (required change to Object.c)
- ported module dictionaries from NMesh
