CodeSnip Old Code (SVN)

Added ContainsSubSet method to ITagSet and implementation in TTagSet.

Corrected in header comments

Modified comments and string literals referring to the "user" database or "user-defined snippets" to remove or qualify the word "user".

Changed native database file "watermarks" to remove the word "USER" and add a UID that is common to both files.

Fixed bug in TDatabaseIOFactory.CreateLoader that was using TDBLegacyUserDBReader when legacy database was not present.

Moved and renamed Src/DB.UDatabase.IO.pas as Src/Main/CS.Database.IO.Factory.pas.
Updated reference in DB.UMain.pas.

Modified various erroneous comments that referred to categories.

Removed temporary Category (ID) property from TSnippetBase and all code that supported using the property.
Updated affected code by removing all references to category IDs.

Fixed bugs in TDBNativeReader's DatabaseExists and ValidateSnippetFileHeader methods. Former was always returning False and latter was testing for a master file watermark instead of snippet file.

Fixed bug in TDBNativeWriter code that deletes unwanted files: it could delete all files in directory!
