Edited signup feature so that user automatically follows themselves. Also created a splash message to instruct user to follow other users, if the user tries to view an empty post stream (due to not following anyone, or no posts being available). Edited the look of /posts/users to point out the logged-in user to themselves, and indicate that they can click on each name for more info. Also, for the modal-dialog profiles, only the fields with data will appear, when the user opens the dialog.
