Mark Liversedge 5fc448c6ab Fix interval painting and lazy delete ...

.. the lazy delete was a horrible hack and memory leak.
   So, now the paint delegate no longer dereferences the
   IntervalItem * from the QTreeWidgetItem.

   Instead we use setData for UserRole+1 to store the interval
   color when constructing the trees. The paint function can
   get this directly and we avoid any contention when the
   intervals are deleted and created.

   The lazy delete can be removed and deleted once the changes
   have been notified via intervalsUpdate().
