randomtrain - script to train on errors

[David Relson]

Greg,

You've been busy!  randomtrain sounds really neat.  Can we add it as a 
contrib?  I'm thinking of splitting your message into contrib/randomtrain 
and contrib/README.randomtrain.

Also, randomtrain can take advantage of the new message formatting 
capability (in CVS).  It's task will be a bit easier with a config file 
that will enables tristate output and puts "Spam", "Ham", "Unsure" (as 
appropriate) on the X-Bogosity line (instead of plain old "Yes", "No").  I 
can patch the script to do this.
