Add +R to channel modes
* +Q - Prevents users from using /kick on a channel
* +N - Prevents users from changing their nick while in a channel with +N set. Can also be used as an extban to prevent a specific user from changing their nick, e.g.: '''/mode #channel +b N:lerxst!*@*''' would prevent lerxst from changing his nick to anything else.
* +T - Prevents users from using /notice on a channel. Also works as an extban (see +N for syntax)
* +b m - Mute - Extban for preventing a user from speaking in channel. e.g.: '''/mode #channel +b m:lerxst!*@*''' prevents lerxst from speaking #channel.
