Paginate with Turbolinks

Finished! I added a way to add/delete comments with pagination. I also included some ajax, so that if you're on the first page you can see the comment being loaded without having to be directed to the top of the page. I also added a way to delete a project, but you can take that out if it's not needed. Sorry it took a little bit. Hopefully someone can make the delete link a little bit nicer (as it's only an ugly link right now).
