Vid 1494

Updates LVS thumbnails to be the new thumbnail version. Also includes some UI adjustments: 
- Videos are vertically aligned when playing
- Removed the ability to close the "more suggestions" portion
- Moved the "more suggestions" text to the left, inside the grey box
- Added titles below the two large thumbnails as they were missing after the thumbnail switchover. 
- Also linted the scss. Sorry for all the minor changes to wade through.
