CodeSnip Old Code (SVN)

Renamed many classes in UView unit and updated using code accordingly.

Changed how database update events are handled:
* New event handler added to TMainDisplayMgr for database view item changes: adding, updating and deletion of snippets and categories.
* Removed category and snippet change handling code from TMainForm's database change event handler.

Reimplemented code that takes care of handling database changes.

* Fixed a few glitches where tab index not being set.
* Now only sends a tab change notification if user explicitly changes tab but not if tab changes as a result of some other action.

Removed all calls to Query.Update. No longer needed in database change event handler since database itself now updates query where necessary after database changes, and before events are triggered.

Changed all code that updates database with changes to user defined items to also update current query.

Fixed problem in TMainDisplayMgr.CategoryChanged method: currently displayed view is now refreshed in case it references renamed category.

Extracted command code in TMainDisplayMgr that re-displays current view in detail pane into new RefreshDetailPage method.

Changed IOverviewDisplayMgr.Display method to have Force parameter to force re-displays of overview treeview. Changed calling code accordingly and to streamline some code in TMainDisplayMgr.

* Changed so that new snippets and categories display in selected tab or in new tab depending on user preferences.
* Fixed error in TMainDisplayMgr.RedisplayOverview to save current tree state before displaying.
