the theory here is that counting the number of sentences generated is
kind of silly, if we're already specifying min/max word counts, we
probably just want to fall into that range, and not really care how many
sentences we get
meanwhile, we were overloading max_sentences to also calculate how long
any one sentence must be, which is kind of a weird thing to derive, so
we're going to drop the max_sentences language and call this more what
it is, a bias towards the number of sentences that might be seen
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
