Moving the `pluck` and `ids` methods to their own delegate line.

These two methods aren't really statistical helper methods and don't
really belong in any other group which is being delegated for querying,
so I'm moving them to their own group of methods.

I've also changed the `:to => :all` hash syntax to `to: :all`.
