Removal of embedded YouTube videos from HackShack

[pattdepanick]

Due to IT Compliancy rukles : HPE DEV site cannot embed youtube videos in any web frame (including HackShack).

The replay page should therefore get all videos linked instead of being embedded in the page. One should not be able to play the video from the hack SHack web page and in the the hackshack web pages. Videos should open up in a new tab and to the youtube url .
