* Added new readloop command 'readgt' which will produce messages with numbers greater than the value supplied in the 'gt' variable.  This of course maps to the 'MSGS GT|xxx' server command.  For my next trick, I will modify the msgomatic selector to use this command, but first, I must find a way to export to the templating engine the value of the first msgnum we retrieved during the *current* operation.
