for convenience, pass a list of events to add_global_regex_handler if
you want to have multiple things fire the same handler. common case is
pubmsg and privmsg
undecided if i'll bother to bring recursion back, but if it works out,
provide this method to either reply or give text to the thing recursing.
either way this is a bit clearer than using privmsg() directly, usually
