Next Release

Opening a PR to prep for releasing all of the changes made over the past several weeks. Before we merge this, I think it is important to figure out the best practice for making the **extra** rules turned off by default (e.g. the ones required by VIP). See #58 #64.

As soon as this merges, everyone using `master` as the source for their WordPress Standard could get a rude awakening when they all of a sudden get a lot of new violations. (PHPCS and the WordPress Standard are now bundled now with VVV, and our Travis CI scripts reference `master`.)
