Tabs der LNO-Docks in Scroll-Bereich packen (#104)

Ein langer Tab (Druck-Tab mit aufgeklapptem Basemap-Bereich) schob den
unteren Rand des QGIS-Fensters aus dem Bildschirm, weil Qt für das Dock
die Höhe des höchsten Tabs verlangt. BaseDockWidget.setWidget packt jetzt
jeden Tab eines QTabWidget in einen QScrollArea; das wirkt auch für
Fachplugins, die ihre Tabs selbst aufbauen. QScrollArea/QFrame im
qt_wrapper ergänzt.
