Title: Add the syncronize action for pull request events

According to the [docs](http://developer.github.com/v3/activity/events/types/#pullrequestevent) there is a "synchronize" event that can occur on pull_request events.

I'll admit that part of the reason I'm opening this PR is so someone can explain to me what the synchronize action is.
