Commit [r516] Maximize Restore History

Made overview pane treeview expansion state persistent when user database is changed by adding, deleting or updating a snippet:

* Added new SaveTreeState and RestoreTreeState methods to IOverviewDisplayMgr and its implementation in FrOverview.pas.
* Added new PrepareForChange and FinalizeChange methods to TMainDisplayMgr and modified TMainForm.SnippetsChangeHandler to call these methods when database changes.
