Support for video embeds

As has gained popularity there might be a need to consider making embeding links as simple as Youtube links. Right now Mega nz videos links can’t even be embedded.

Mega nz links do not point directly to files, but rather to a Mega Media Player just like a Youtube did some times ago.

This is an example of a video link that should be recognised as a video embed.
