Add support for embedding YouTu.be URLs

Allows you to embed them. Needs to be transformed internally as their oEmbed provider doesn't support them. Adds a new filter to do it.

Could we not just register youtu.be as another oembed provided and rely on the 302 following of the HTTP handlers.

That way we don't need any youtu.be specific code in here and if they change the url format of any of the providers in future and offer 302 redirects we would follow those too?

No, because their oEmbed provider doesn't understand their shortened URLs.

Example short URL: ​http://youtu.be/nTDNLUzjkpg

Their provider returns a 401 for that URL: ​http://www.youtube.com/oembed?format=xml&url=http%3A%2F%2Fyoutu.be%2FnTDNLUzjkpg

Ideally their oEmbed provider should support their short URLs. I didn't think that'd be possible, however I recently saw one of the YouTube people post to the oEmbed mailing list, so I'll see if I can get them to support their short URLs so we can just map them directly to their oEmbed provider.

YouTube's oEmbed provider now understands shortened URLs.

Sweet. :)

Actually, we still need to add that format to the whitelist, we just don't need a remapping function.

Oops, yep.

Whitelist youtu.be

(In [13203]) Add Youtu.be short URLs and Smugmug to the default oEmbed providers. Props Viper007Bond, fixes #11556, fixes #12157
