[Bf-funboard] Unified editmode

[Tom M]

Briggs brought up an issue regarding editmode - currently if you need
to do a task such as say snapping all the verts of a lattice to the
verts of a sphere  or aliging points on a mesh with control points of
a nurbs - this is extremely difficult to do, since only one object can
be in editmode at a time.

Thus it would be nice if objects of different type could be in
editmode at the same time (currently you can join mesh objects so it
is possible for the same object type to be in editmode).
