What does this implement/fix? Explain your changes.

Currently there is no authoring component for embedding external content from ad networks or social media.
Twitter Embed
Youtube Embed

Does this close any currently open issues?
No. I've mentioned the issue in the past during the water-cooler and Gaston has also faced issues embedding external content.
Any other comments?
I still don't have a strong grasp on the percli commands needed to create and update the components. Could not find the docs that really explain the process. So I used

manuallyWhere has this been tested?
