CodeSnip Old Code (SVN)

Added support for reading and writing a tag set in master file in database load and save operations.

Modified code that tidies up files after a save operation to delete any file that doesn't belong rather than just known deleted snippet files. This ensures that any legacy files are removed after the database is saved in current format.

Changed type used when reading writing a snippet's RequiredModules property from a list of 32 bit sized strings to a list of 16 bit sized strings.
Also simplified methods used to write tags and properties with ISnippetIDListt types.

Reimplemented code that reads and write a snippet's Tags property and properties with ISnippetIDList types.

Added new IStringList.IsEmpty method and its implementation in TIStringList.
Modified all code that tested IStringList.Count against zero to use IStringList.IsEmpty intead.

Changed format used to read/write a snippet's CompileResults property: a 16 bit sized string list containing the ID strings of compilers that can compile the snippet is immediately followed by a similar string list of ID strings of compilers that fail to compile the snippet.

Simplified TDBNativeReader.ReadMarkup by using TActiveTextHelper to perform REML parsing. Also added error trapping for bad REML code in database files.

Made minimal type and implementation change to get the unit to compile in the "parsnip" source tree.

Copied CS.Database.IO.Native.pas from "experimental" branch to "parsnip" and added to project.
