View3D: snap menu (SHIFT+S) back.

All options are own operators, a (temp?) menu collects them all.
Note that the operators have a full name, for the menu it seems
too much; still I'd prefer a way to name operators in a way
it fits everywhere. That will make a unified translation system
possible for example.

Also: this code was needed to get 'center view' (numpad dot) in
editmode to work.

Last note; it uses old transform code to gather vertex info.
This is fully local to this C file, and quite simple to replace 
in future with new transform.
