The user should always be informed of a mode change in a channel. Biboumi does not need to interpret the meaning of these modes, except for the modes towards a channel user:
- mode +v means the participant is a member
- mode +h means moderator
- mode +o means admin
- mode +q means owner
In all cases, biboumi should forward a message to the MUC saying what mode was set, by who.
