2.5: Object module

* Split object_edit.c into multiple files:
  object_add.c, object_edit.c, object_hook.c, object_relations.c,
  object_select.c, object_transform.c.
* Rename files to have consistent object_ and mball_ prefix:
  object_shapekey.c, object_lattice.c, object_vgroup.c, mball_edit.c.
* Added operators:
  * vertex group menu and set active
  * apply location, rotation, scale, visual transform (location is new)
  * make local
  * make vertex parent
  * move to layer
  * convert to curve/mesh (not finished yet)
* Many small fixes for marked issues, but still much code to be cleaned
