Push/Pull (aka: non proportionnal resize, original idea by Robert Tiess) slipped in my last commit a bit, so might as well finish it.

Accesible with Shift-P (was free), the behavior is much like Shrink/Fatten. Pull mouse toward you to pull toward center, push away to push away. Constraint and PET works with it too, of course.
