SUPPRESS-GO-AHEAD

This supports suppressing or activating Evennia
the GO-AHEAD telnet operation after every server reply.
If the client sends no explicit DONT SUPRESS GO-AHEAD,
Evennia will default to supressing it since many clients
will fail to use it and has no knowledge of this standard.

It can be activated explicitly with the ADDGOAHEAD option.
