Hotkey to toggle glassy-gnome for some windows

Hi,

I need to disable glassy for some windows on demand via hotkeys - like one non transparent Firefox window but the other Firefox windows remain glassy. I propose the following patch in the hope that it will be useful to someone else. It uses Supr-7 to toggle between enable/disable state.
