Save / Restore the Tree after organizing by other columns.

Browse source 
This patch saves and restores the state of the TreeView after the user
clicks on another columns that will make the tree disappear. All of the
branche states are saved, this way the expanded nodes will be restored
when the user gets back to tree mode.
