Remove junk files
Refactored MeTube home view. Uses partials and loops to make sections

* Partials are loaded through the `@include` directive in the Blade
  templating system.
* Removed a lot of redundancy.
Refactored Browsing into single controller, abstract pagination

* All the browsing functionality was essentially identical, meaning
  that it could be refactored into a single controller and use the
  same view partial to render the media previews.
* Abstracted Pagination into a partial that should be usable anywhere
  in the application.
