CodeSnip Old Code (SVN)

Changed XRefs search to use TSnippetID and ISnippetIDList types in preference to TSnippet and TSnippetList wherever possible.
Also changed TSearchFilterFactory.CreateXRefSearchFilter to take a TSnippetID parameter instead of a TSnippet. Modified calling code accordingly.

Renamed TSnippet's DisplayName property as Title and modified affected code accordingly.

Replaced unnecessary calls to FreeAndNil with calls to object's .Free method.

Removed UserDefined property from TSnippet.
Made minimal changes to affected to code in order to compile. Inserted TODOs where further consequent changes are needed.

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