------- Additional Comments from Mario Sanchez Prada <msanchez at igalia.com>
The previous patch got	a bit outdated again, so now attaching a new one that
applies cleanly against today's trunk.

I also made the most of this to re-implement the unit test in a different way,
using a new subclass of UIClientTest (ModalDialogsTest) to avoid adding some
"ifs" to check whether it was a "modal dialogs" test or not.
