UI: tracks drag & drop + minor fixes

Allows tracks to be reordered by drag&drop, supporting
also D&D between scrolling and pinned containers.
Furthermore bunch of small fixes:
 - reduce the track shell width to 250px, was taking
   too much real estate.
 - fix off-by-one pixel caused by the track bottom
   border. The border was being over-painted by the
   track shell having a bg:white. Now it's a border
   shifted back by 1px, so the track stays at full
   height but the border is always overlaid on top.
- Reduces the font size of the track shell.
- Fixes ui_unittests.
