Title: Fix Gravtastic Setup Instruction

The original instruction for `Gravtastic` has `rails g gravtastic:install`, which does not work (`Gravtastic` does not have a generator). A mixin to the `User` model is, however, required [according to the documentation](https://github.com/chrislloyd/gravtastic).

I also include some minor formatting fixes.
