HaikuDepot: Scrollbars for content, document window look

* All text views that potentially need scrolling are now
   embedded into a CustomScrollView. That one controls a
   vertical BScrollBar only and has B_NO_BORDER frame. Since
   the regular BScrollView doesn't do some adjustments in
   this setup, the CustomScrollView takes care of moving the
   BScrollBar such that the B_DOCUMENT_WINDOW_LOOK resize
   handle does not obscure the bottom arrow button.
