Changed UsersController#index to use will_paginate plugin instead of classic_pagination

Made corresponding change in view.
Added User.per_page method to provide number of users per page to User.paginate button.  I can remove and just pass the param to the method in the controller if that is more desirable.
Added 2 controller tests for pagination.  No view tests have been added.
