[compiz] [PATCH] Add override_redirect matching support

[Erkin Bahceci]

Hi,
Here is a patch that adds override_redirect matching support to
match.c, allowing expressions like:
    override_redirect=0
or like:
    (type=Unknown | Menu) | override_redirect=1

This is necessary to be able to match popup and dropdown menus in
Mozilla applications.

Regards,
Erkin
