We now have the Embed Media plugin installed. To use it, put in the the full url of the media to be linked and surround it with the [media] and [/media] tags. For example: [media]https://www.youtube.com/watch?v=cl3B_FTDKD0[/media].
In full post mode, there is also a Media button right above the composition window at the end of the row of buttons there.
In addition to Youtube, the Embed Media plugin supports a bunch of different websites.
