Plans for front of card.

It would be nice if I could just send SVG to the browser and let it
print. Or even HTML. But getting Firefox to actually print 1" as 1"
appears undoable. Margins are real fight, too.
Camera now works.

Very hackish, because User Media API is in a huge state of flux, and no
browser implements even half of it. Server doesn't handle the data yet.

TODO: Make this work in Chrome.
Now with Chrome support & cancel button.

Now works with Chrome. And has a cancel button.
