Drop popwin and borderwin from owl_popwin Again, the WINDOWs are effectively owned by their PANELs, so we remove the extra reference to avoid possible inconsistency. Because del_panel fails to delwin, we need a little dance to delete both at once. A future abstraction layer should take care of that.
