CodeSnip Old Code (SVN)

Removed unused TDatabaseIOFactory.CreateUserDBLoader.
Also removed all unused interfaces and classes.

Changed TDatabaseIOFactory.CreateWriter to return an IDatabaseWriter instance that writes database in native format.
Re-ordered code in TDatabaseIOFactory.CreateLoader.

Updated re changes to unit and class names for empty database reader at revision 4267.

Added new TDatabaseIOFactory.CreateLoader method that can create and return a database loader object for a database in either native format, legacy format or return a null loader if there is no database present.

Renamed IDatabaseLoader and _IDatabaseLoader to avoid clash with new interface of same name. Also renamed IDatabaseWriter as _IDatabaseWriter as a precaution.

Fixed bug in code that creates a tag for every category loaded from (old style) database file.

Renamed TSnippetList defined in DB.USnippets unit as _TSnippetList and modified affect code accordingly. This is a first step towards changing snippet lists throughout the code to use a different list type.

Removed unused UserDefined parameter from TCategory.Create and IDBDataItemFactory.CreateCategory and made necessary change to using code.

Added new fAllTags ITagSet field to _TDatabase and ensured any new tags are added to it.
Modified database loader to update fAllTags (indirectly) when database is loaded.

Fixed problems setting snippet references and tag set following changes made to TSnippet at revision 4034.
