[virt-tools-list] [PATCH] timed-revealer: listen to the "grab-notify" signal

[Fabiano Fidêncio]

The "grab-notify" signal lets us know when our widget becomes
shadowed by a Gtk+ grab on another widget, or when it becomes unshadowed
due to a grab being removed.

That's exactly the case we face when dealing with "usb-redirection" and
"close" items of the fullscreen toolbar. And, currently, when these
widgets get closed the timed-revealer stays there forever. From now on
let's take advantage of the "grab-notify" signal and schedule a timeout
for the revealer when these widgets' windows get closed.
