CodeSnip Old Code (SVN)

Changed type of TSnippet's Depends and XRef properties from TSnippetList to ISnippetIDList.
Made minimal changes to affected code re the type changes.

Added new Remove and IsEmpty methods to ISnippetIDList and its implementation in TSnippetIDList.
Added support for IClonable interface to TSnippetIDList.
Reworked TSnippetIDList.Assign.

Merged revision(s) 3896 from branches/parsnip:

This reverses revision 3896. The CS.Database.IO.Legacy.UserDB unit had too many differences to the current database code in "parsnip" to be easily integrated.

Copied CS.Database.IO.Legacy.UserDB unit from "experimental" branch into "parsnip" and added to project.

Added new unit containing an implementation of ITagSet.

Note: this is NOT a copy of the unit of the same name in the "experimental" branch.

Some tweaks to ITagSet.

Replaced ITagList with ITagSet interface and supporting closure type.

Removed "DB" from any identifiers associated with tags.

Modified TDBTag to validate tag ids and to use tags as provided instead of replacing spaces with underscores.

Fixed TDBSnippetID and TDBTag hash functions.
