Querki should allow embedding, similar to how the everything from Medium to Gitter do

Summary: There are now "embedding as a service" systems that make it relatively easy to just specify a URL from an "embeddable" service, and the resulting stuff -- videos, maps, whatever -- just shows up.

There are at least two of these services, embed.ly and iframe.ly. Neither is free, although neither is insanely expensive. (Basic plans in the $10-30/month range, solid ones for $99 or so.)

In principle, we could totally do this ourselves. The advantage of these services is that they deal with pre-screening the services and suchlike.

What would this look like in Querki? We'd need to have some sort of way to say "embed something here", both in QL and as a type, I think. We might allow it in Conversations, although that requires more care and thought.
