CodeSnip Old Code (SVN)

Renamed CS.Database.IO.Null.pas as CS.Database.IO.Empty.pas and renamed TDBNullReader as TEmptyDBReader.
TEmptyDBReader.Load now passes out the current date instead of a null date.

Changed TDBNullReader.Load method to clear the given snippet table as happens in other database loaders.

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.

New unit containing a null database loader class for use when there is no database present.

Corrected error in code that checks for correct XML processing instruction.

Removed unused parameter from IDatabaseLoader.DatabaseExists method and its implementation.

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

Added 2nd "False" parameter to all occurrences of TFile.Exists: this prevents symbolic links being followed.

This is similar to the change made in "parsnip" at revision 4258.

Future proofed some code against any future Win 64 port of CodeSnip.

Added 2nd "False" parameter to all occurrences of TFile.Exists: this prevents symbolic links being followed.
