Implement "your videos" tab

[Mikescops]

This is a fix for request #277.

It implements a new "Your videos" tab and the ability to filter a bit more mime types when requesting photos.

I'd like some guidance for the needed translation.

Also there is a limitation on array merge that is fix only on PHP7.4 with the spread operator.

It is sightly different approach than #392, same limitations indeed.
Hope we can bring back the topic on the table.

Rebased with latest master.

It’s still a bit strange to have the videos filtered if they show no previews at all. :\ Hope we still find a solution there, also ref the discussion from @jakobroehrl’s pull request in #392

[Mikescops]

So I suggested an idea to @skjnldsv, when there is no preview, we display the name of the video in the tile. Also we can suggest with a banner a way to activate video previews

Both nice enhancements! :) The banner should only show to admins though who can actually make the change.

@Mikescops can you open issues for those? :)
