Fixed direct video links not rendering correctly.

Fixed direct video links not rendering correctly.
Added webp and webm formats.

---

Direct video links[1][2] were not being rendered correctly and I were always showing a message:
Your browser does not support the video tag.

I did some changes to correctly create a <div><video><source> structure so that the video is rendered correctly.
Still need to update the tests in basic.t and clean up the %for in the video.html.ep template.
And the video is being rendered at 100%, so that needs some cleanup too (review class and width/height).

Could you please take a look already to see if you understand what I did?
Maybe provide some guidance/comments?

I think this looks great in general. Just need some tweaks.

Thanks for the contribution!

I did a round of changes and fixed the basic.t tests.
I'm checking it it was me who broke the other test... I'm having failures when using TEST_ONLINE=1 on some others tests.

I'll rebase and merge this once you have pressed the "Ready for review" button 👍
Feel free to make more changes though, if you want to.

I think I did most of what I was planning.
I'm glad to accommodate any other suggestions.
If there's nothing else you would like changed related to this, feel free to accept it.

I was wondering if there's something else needed to better integrate the changes in convos... but I do not know the code base well enough to give an informed opinion about that.

Not sure what that would be, but please let me know if you have any specific ideas.
