4) Restrict upload for authorized users only
Right now, all of the pages are accessible for everyone even for unauthorized
user. We need to fix that.

4) Implement frontend layout
Delete the layouts folder in frontend > views and copy the layouts
folder containing main.php, blank.php, _sidebar.php, and_header.php
from backend, and basically do the same thing we did to the backend with a few
modifications. Also copy the site.css from backend and paste it to the
frontend and remove the css for icon style.

5) Display video uploads based on specific id
Let's say there's another user. Right now, with the current code, when they
logged in and view the Video page, they can see the uploads by another
account. This is very bad so we need to change this.
