CodeSnip Old Code (SVN)

Changed history so that updating a snippet no longer clears the history.

Changed TSnippetView's constructor and TViewFactory.CreateSnippetView to take a TSnippetID parameter instead of TSnippet.
Modified calling code accordingly.

Changed data type for change events involving snippets passed via Info property of IDatabaseChangeEventInfo from TSnippet to TBox<TSnippetID>. Modified change event handlers in using code accordingly.
Also added new code to generate an IDatabaseChangeEventInfo.Info property value of TBox<TTag> ready for when event re changes to tags need to triggered.

Moved all change event handling code from _TDatabase into TDatabase and removed AddChangeEventHandler and RemoveChangeEventHandler from _IDatabase.
Relocated TDatabaseChangeEventKind and IDatabaseChangeEventInfo within DB.UMain unit to be visible to TDatabase.
Modified all code that called AddChangeEventHandler and RemoveChangeEventHandler from _Database object to call methods on Database object instead.

Removed event kinds that applied to categories from TDatabaseChangeEventKind.
Modified affected IDatabaseChangeEventInfo event handlers

Modified various erroneous comments that referred to categories.

Renamed various interface, class and factory method names in UView.pas to correct the spelling of "Null" in their names.
Modified affected code accordingly.

Renamed IDatabase and Database function, along with internal TDatabase class and PvtDatabase varibale by placing underscore in front of their names. This is to flag the items as "legacy" and to avoid name clashes with new database code being developed.
Modified all code that calls Database to use _Database instead.

Recreated "parsnip" (v5 development) branch by branching trunk just after updating it with changes in v4.7.1.
