Batch renaming with the Vertex Groups Renamer add-on

Gilad writes:

The batch renamer that blender have is great! but you can't use it on your vertex groups.
So... if you need to change the names of your vertex group, now you can!

With "Vertex Groups Renamer" addon you can add prefix/suffix for all of your vertex groups, find and replace and set the case state of your vertex groups name (upper \ lower case, etc...)
