About the only place where we are guaranteed to get all the players'
names correctly is in the seating plan in the hand header. We extract
the names and build a regex that matches only the names. We only do this
if the current regex is out of date, to avoid recompiling them too
often.
I also did away with self.rexx because it seemed unnecessary and was
difficult to work with.
