task #12499, filter mode changes after joins: http://savannah.nongnu.org/task/?12499
+"When you see a mode change it's not "MODE" command received but a numeric command (for example 324 for channel modes). So you may have to ignore many numeric commands to ignore all modes." -- http://forums.flashtux.org/viewtopic.php?p=106&sid=62c78f547fb166200ca839a0d08d96d4#p106
