Don't switch pages when dragging out of folder

-> Fix bug where page switch indicator wouldn't draw on right
-> Fixed some code related to folder reordering -- no behaviour change
   yet, but once the new AutoScroll is in, this should behave correctly
   (ie. shouldn't reorder while in scroll zone)
