Workaround a lack of API from Qt where it will decide to move the panels
around without us being able to control it.
This patch overrides the QWindow::screenDestroyed slot to be able to decide
where to move the Panel or whether it needs to be removed. This is
considered a workaround and should be removed once the new API is in and
released.

This way, we don't need to have everything being repainted when geometries
change while constructing the panel.
Also don't connect to screen changed until everything is initialized and
the panel is displayed.
This broke screenForContainment because the Panel didn't know where it
would be placed when the panel is being set. This shouldn't be the case
anymore.

CCBUG: 334502
At the moment the Panel didn't have any code to react status changes from
the containment (and therefore its applets).
This patch aims to add this, only problem being that it doesn't work. The
"unhide requested" and "unhiding" messages are being displayed though.
I've been looking for the code that does the actual display of the
auto-hiding panels and I wasn't able to find it, help is welcome.
