Embedding videos and more on the forum

Was looking how to do it b/c iframe code didn't work, then found this:

https://meta.discourse.org/t/how-to-embed-youtube-and-other-videos/5623/6

This feature is called oneboxing and works with a lot of different formats, like PDF, MS-Office Docs, URLs, GH-Links etc. I didn't find a documentation that lists all the content-types though.

Basically you put the video URL on it's own single line and it is embedded, like here.
