As of now, this module doesn't need text.js, so don't load() it.

Use the proper method of detecting an ANSI terminal:
  console.term_supports(USER_ANSI), not (user.settings&USER_ANSI)

Use a user-property, [logon] makguest=false, rather than the 4G flag to
indicate that the sysop has opted-out of creating a 'Guest' account on their
BBS. If you don't have an Guest account and you already opted-out, sorry, this
will prompt you again. However, get the use of a security flag (4G) back for
your own definition/use, as originally intended.

Removed some commented-out debug output (clean-up).
