RFE make selection modes on JTree consistent with those on JList / JTable

* JList and JTable each have a setSelectionMode method, JTree does not (requires calling
  setSelectionMode on it's selection model)
* calling setSelectionMode on JTree's selection model changes the selection, calling it on
  JList and JTable's
selection model does not (will leave the selection invalid when multiple
  rows were selected and changing to SINGLE_SELECTION)
* we can listen for changes on JTree's selection mode, on JList and JTable's selection mode we
  can not
* DefaultTreeSelectionModel uses a DefaultListSelectionModel, however changing the selection mode
  on one does not change it on the other, we even use TreeTables sharing the same listSelectionModel
  which means
we have to do extra work to make sure that when the selection mode is changed on the
  listSelectionModel we also change it on the treeSelectionModel (and vice versa)
