Changeset 5620 for data/trunk/levels

Readded a slightly modified version of princessaeryn.oxw (the old version is still in levels/old). The notifications seem to still work.
Also removed the notifications from the default HUD because the NotificationQueue is actually an OverlayGroup and therefore can't be added to another OverlayGroup currently (this always triggered a warning). Notification still works because the NotificationQueue is in the levelfile.
