Versions as playable Attachments to Notes


We're often attach Versions as a proof of the updated/fixed work to a comment. Version appears as web link and this is actually not quite convenient because:

- we don't have a cool preview thumbnail, as we do have on versions.
- clicking on web link opens version's details page, not the version itself, so you have to click one more time to actually view it.

It would be great to treat attached Versions in a more special way, so we can see a (scrollable on hover) thumbnail with a play button, and clicking on it would open up the web player directly:
