-> Make Face Edge tool

Return of the fkey 'make face edge tool'.

As always, selecting two vertices will make an edge. Selecting
three or four verts/edges will make a quad. Additionally selecting a single
closed loop of edges will create an n-gon.

Still to do:

-add back in the 'fix faces' call at the end to generate proper smooth flag
for generated face

-add a 'fuse faces' tool bound to this hotkey. This will replace both the
'join triangles' functionality of the current f-key implementation as well
as the f-gon creation (replace with n-gons)
