So, editmode mesh is back! :)
At the moment only TABkey works and mouse select, 1 vertex at a
time. More will follow of course.

Note for the devs:
- G.editMesh has been removed, be careful with old code.
- EditMesh now is property of Mesh itself
  Although it means unlimited editmodes, for migration purposes we
  better stick to 1 "obedit" per scene, which is in Context too
- G.obedit will get removed soon, so use CTX_data_edit_object(C)
  Or if you can't, just scene->obedit for now
- Also removed the CTX_data_edit_mesh(), this has no meaning 
  anymore. EditMesh is not context senstitive anymore, only the
  edit-object for time being is.
- Martin: I've already tucked some EditMesh pointer in T and
  removed all G.editMesh there.
