Added vertex weight python scripts accessable from the paint menu.
* clean weights (removed low weights)
* normalize, maximizes weights to a user set peak, optionaly scales other groups too to keep the proportion of the weights even. (Doubles as a weight scaler)
* Grow/Shrink, uses the mesh topology to expand/contract the vert weights. a few options for iterationsm, max length and strength.
I need a way tell if the users in Face Select mode (in python) so I can make use of the selected face flag.
