Please finally support MP4 embeds (for Bug reporting etc)

I don't mind writing bug reports and such or show the bugs to the devs here on the forum. But it's really super annoying and a huge waste of everyone's time to

* upload to youtube only to embed a 5 MB clip
* convert to gif and compress and eye-rape everyone with automatic play

For a clip of size of 5 MB one might as well embed the MP4 file instead of the animated gif. It's cleaner and has a considerably better compression and playback ratio.

It would be really super helpful if Unity would support MP4 files here on the forum that users can see a preview and play back whenever they want to.
