Thumbnails for exported projects

[benrito]

Can we create simple thumbnails as part of the render queue? This would help user's projects stand out when sharing via social media.

The really cool thing would be to make these animated GIFs but that might be hard.

Let's embed the project metadata inside so we can use Tracey's awesome feature in #61

sounds good!
we can do this easily on server-side REST API (could host at archive.org)
or w/ some more work, for some(/most/all?) modern browsers, we could do it in the client in JS...

(grab current project's JSON and inject it into a thumbnail. for all clientside/JS -- we'd also likely need a little something to hook in to "generate thumbnails" in JS, too)

@traceypooh i think that @antiboredom's render pipeline can create thumbnails for us.

i bet it could even create animated thumbnails...
