Title: Changing set_workers to ps_scale

Apparently, though still a method in the gem, set_workers doesn't work anymore. See here: https://github.com/heroku/heroku/issues/263.

I have updated things and confirmed that they're working on my app. I was not able to get the specs to pass (though I tried to update them as best I could), but I'm not exactly sure how they're supposed to work.
