Enhanced CSS support

Version 2.06 now provides for generic CSS entries to be made via the setStyleEntry method. Updated the Template Module and Normal Module to use this/be aware of it. See website for some examples of it in use. (hint - move your mouse over the links. The menu hasn't changed.)

Incorporated cgi-lib.pl as HTMLObject::CGILib. All programs/examples I distribute have been updated to reflect the change. This alleviates having to have cgi_lib.pm or cgi-lib.pl in your cgi-bin directory.
