Include binstubs generated by Rails 4

Commit b516ecc added `bin/` to the .gitignore file. Now that Discourse
runs using Rails 4 by default, however, we should include the binstubs
generated by `rake rails:update:bin` in version control as this is the
recommendation of the Rails core team. Additionally, for those wishing
to deploy Discourse to Heroku, these binstubs are actually mandatory
according to [this article](https://devcenter.heroku.com/articles/rails4).

Other binstubs can continue to be ignored.

Extract queries to keep logic in the Categories Model

This creates two methods in the Category model. This moves the model
logic to the model and just calls the Category class methods in
ListController.

This also adds tests for the two methods created in the Category
model. The motivation for this refactor is the code climate score of the
this class and readability of the code.
