add some anti-flood protection stuff 

this throttles multi-line messages in a way that probably doesn't affect
the normal cases much, and scales fairly well to far longer text. for
some reason long ascii art still triggers the flood detection, but with
this code at least it happens later in the process. so, success, for
now? i can fix the ascii art at some future point if i ever hit it
practically
