_NET_WM_STATE_DEMANDS_ATTENTION support

[GoogleCodeExporter]

The _NET_WM_STATE_DEMANDS_ATTENTION atom is part of the EWMH specification and 
can be used to indicate that something happened in a window. It's apparently a 
somewhat weaker hint than the urgency flag of WM_HINTS, because EWMH say that 
windows expecting immediate attention should still use WM_HINTS.

Either way, the current UrgencyHook doesn't respect 
_NET_WM_STATE_DEMANDS_ATTENTION. This impacts amongst others all Qt 
applications, since Qt only uses ..._DEMANDS_ATTENTION and never WM_HINTS.

I patched UrgencyHook to also respect _NET_WM_STATE_DEMANDS_ATTENTION. I'm not 
much of a Haskell expert though, so I suggest someone takes a good look at it 
and point out what I did wrong.

Thanks Maarten. I've pushed the patch as-is. Some things might be done with 
less code:

dpy <- asks display

instead of

dpy <- withDisplay (\dpy -> return dpy)

But I don't have any actual errors to point out.
