fixed a bug in poly redux's vgroup weight merging (was reducing the weight each collapse by about half)

Browse Source 
fixed some other UI logic in the python menu script
Added an option to use a vertex group for a reduction weight map to force reducing some areas more then others.

Mesh epydocs activeGroups can be None as well as string.
