Ignore words

[phillc]

Hello,

I'd like to contribute a patch that ignores messages that contain a regex. However, I can't figure out how to test this package.

I want to provide a list of regexes like /lol/,/\@/ in I guess an env var like HUBOT_MARKOV_REJECTLIST. I believe I would iterate over them and check them right after the username ignorelist https://github.com/smashwilson/hubot-markov/blob/master/src/default-listeners.coffee#L81.

Let's say I have a local copy of hubot running, perhaps a symlink from the node_modules directory to my local copy of hubot markov? Also with my env var set. Do I just type in some words and see if it catches them or do you have another mechanism?

My primary motivation is to reject messages with # or @ in them, in slack the # references other channels which makes weird sentences, and the @ notifies people, and when markov repeats them it actually notifies them (we've had a couple @channel's).

Thanks
