Configurable prefixes for chanmodes +qa: prefixes can be turned on or off individually and seperately, per server as well as per mode, and prefixes are no longer limited to ~&. *** SERVICES AUTHORS *** This involves a protocol change. FJOIN now sends the userlist with format modes,nick instead of prefixes,nick.
