when the pane position is changed update the user option

The slightly awkward implementation with the first allocation flag is necessary because the initial window creation does not cause an allocate-event signal so the position value in the pane is incorrect and we cannot know what it should be until after the allocation (which did not generate a signal) is done as the user position is a percentage of pane total width not an absolute value.
