[PATCH] Unset mouseGrabberPopup if it's removed from children The mouseGrabberPopup is supposed to be unset in handleRelease, however when the exit transition of the mouseGrabberPopup (that closed itself on button press) finishes before the release event is delivered, it unparents itself from the overlay (see QQuickPopupPrivate::finalizeExitTransition) and the overlay sets itself invisible if there is nothing else visible in it. Because the overlay is not visible it handles no events anymore and the release is missed and the grabber is never unset. When opening another non-modal popup the overlay then will continue forwarding the events to now invisible popup. So when the overlay loses the currently grabbing popup as a child we need to reset mouseGrabberPopup.

disable examples using fontello fonts. There are two examples using the embedded fontello font. As the fonts is not in it's preferred form of modification we needed to remove them. Also the fonts are not letters, so they can not be replaced with another one. . So we disable the build of this to examples.
