Log Message:
-----------
'Fix Deforms' op added to weight paint tools to smooth (remove/reduce) spiking caused by bones by altering vgroup weights
--it's still really simplistic (and slow!) so don't try fixing an entire mesh! xD
Also, don't use it on a mesh with a mirror modifier yet, just noticed that it does both vertices instead of one.
Minor UI text update for Vertex Masking
