[sugar] [PATCH] Add notifications to XoIRC

[Tomeu Vizoso]

Hi,

here are two patches to XoIRC:

0001-Fix-windows.patch

windows.py  and widgets.py references each other, so windows cannot
use a constant from widgets in its method declaration.

0002-Emit-a-notification-when-someone-addresses-to-us-and.patch

Send a (very simple) notification when a message addressed to us
arrives and the activity is not visible.

Thanks,

Tomeu
