rfr_ Adding pagination

Added pagination + specs for the user page available to the admin and to the bus page available to the user.
Because you don't have any alternate contexts, a context block isn't useful/necessary here.  (Context blocks are useful if you have a bunch of tests, some of which related to one set of conditions -- e.g. where a user is authenticated -- and others that related to a different set of conditions -- e.g. where a user is NOT authenticated.  They provide a nice way of organizing your tests.)
