Qt has problems initializing everything correctly if there is no screen at startup. E.g. the breeze widget style tries to initialize some pixmaps and this fails. In worst case hitting asserts in Qt (debug build). This change creates a dummy screen which gets destroyed as soon as there is a real screen. Reviewed-By: notmart and sebas
