I've made it so that just updating the master branch of https://github.com/techcorridorio/slackin will deploy to Heroku. We just need to automate that (maybe with a smoke test).

Need to automate what, updating https://github.com/techcorridorio/slackin when https://github.com/rauchg/slackin master updates?

I was thinking something like that. It can be done via a GitHub pull request too. See #17.

Anyway, I just don't want our slackin to get too far out of date.
