Harbour dialect missing commands

[cpyrgas]

Those commands where found in a Harbour app and are missing from X#:

set bell off set esca on set talk off set stat off set safe off set scor off set conf on set PROC TO lib

These should not be too difficult to implement. For some of these the member in the Set enum is already there, but we're doing nothing with them. The question becomes: what to do with them. Most of these are related to the CLipper GET system

Robert, I'm playing with the get system right now, let me work on it a bit more and will come up with suggestions/implementation.
