    - Fix background when changing display direction
    - Add background colouring functions; fix highlight bug
    Previously when in combat, if a rotation list was edited (someone was
    removed or the order rearranged) the highlighting of frames did not
    update properly. Observed bugs were:
    
     -    if the next interrupter was removed, when that frame was reused by
          the FramePool, it would still be highlighted
     -    if the order was rearranged incombat, the highlighting would not
          update to reflect this
     -    when leaving combat, if the highlighting was desynced from the
          rotation it would not unhighlight everything
    
    To fix these issues general use background colouring functions were
    added to display.lua intended to be used for all highlighting puposes.
    The colouring of new interrupter frames was moved out of InitFrame (as
    this function only fires when a new frame is created, not when reused)
    fixing the issue of reused frames being highlighted and colouring of a
    list is now done after rearrange.MouseUpdate which is when the
    rearrangement of the order takes place.
