Videojs update & safari adblock fix

- Re-forked videojs, videojs-vast, videojs-contrib-ads (safari adblock fix required changes to all three)
- Clean " - video" from video headlines on video pages

Most of the videojs-vast / videojs-contrib-ads diffs are changes pulled from the main repos while updating, so they can be safely ignored. I'll be putting in PRs to the respective repos.
only want to remove this from the end, not from anywhere else... 
no idea if it will ever appear anywhere else but can't hurt to do it this way right?
