[compiz] [PATCH] Role window matching

[Bellegarde Cedric]

http://hibbert.univ-lille3.fr/~cbellegarde/Compiz/role_match.patch

This patch add a new match type in regex plugin.

You can now add a "role=" in match strings...

This will enable me to put window matching into bs plugin and remove 
Opacity/Brightness/Saturation window matching from state plugin (currently in 
conflict with opacity window matching from core).
