* Fixed a bug with IDENTIFY courtesy of Foobar, added proper response numeric.
* Fix services helper commands so that if a user doesn't pass a : to designate
  an IRC string, we make sure it still goes through.
* ! Cleaned up the whole ugly set_chanmode() function, hopefully making channel
  mode synchronizations sane.
* Added O:Line permission flags as per Bahamut 1.4, added two extra oper flags:
  "S" checks against the BBS system password instead of the O:Line password,
  and "x" enables use of the "DEBUG" and "EVAL" commands.  "x" must be
  explicitly enabled.
* Added some preliminary support for N:Line server flags.
* /ctrl/ircd.conf was rewritten from scratch to sane Synchronet IRCd defaults.
