Add Video Previews to Attachment Field

[jamesvclements]

Video support is really limited at the moment:

Attachment fields support videos, but it’s not super useful for managing video content as you have to actually click into the content to see what it is.

It would be a huge help if the table views supported video embeds or at the very least static previews of the video, instead of the play icon.

Posted this before I saw the video snippets app. This definitely helps, but doing this by default in the gallery view / enabling it as an option in other views would be really useful.
