- this option has been a default option flag for 10 years
- this option was introduced *before* the RLogin password capability
- Synchronet now always expects the login-ID (alias) to be the 2nd string
received during RLogin connections (called 'server-user-name' in RFC 1282.
* Now storing the complete terminal type/speed string received during RLogin
connection in the bbs.rlogin_terminal property (sbbs_t.rlogin_term in C++).
* bbs.rlogin_gate() is over-hauled:
- arguments are: address, client-user-name, server-user-name, terminal, mode
- if existing JS module assumes this to be: address, server-user-name, password
  those scripts will need to be updated to reflect the correct argument order
- all arguments beyond the first are now optional
- the terminal string can now be passed-in
* Deprecated the telnet gateway option: TG_SENDPASS (the 'password' if desired
to be sent as the 'client-user-name' can be specified as an argument and this
option sent the password as the *second* RLogin string ('server-user-name'),
which was always wrong.
* sbbs_t::telnet() can now accept the terminal string as an optional argument.
