yfrog provider missing width/height, video support: should pass through to yfrog's own provider

What steps will reproduce the problem?
1. Go to oohembed result for a yfrog image:
http://www.oohembed.com/oohembed?url=http://yfrog.com/f5fjuhj

What is the expected output? What do you see instead?

Photo output must include width and height parameters per oEmbed spec, but they 
area missing here. The good news is, yfrog now has their own oembed endpoint 
which includes that information:

http://code.google.com/p/imageshackapi/wiki/OEMBEDSupport

Sample:
http://www.yfrog.com/api/oembed?url=http://yfrog.com/f5fjuhj

It should be possible to replace the current yfrog photo and video provider 
code with a passthrough. (yfrog's pages don't include discovery links, so 
services like StatusNet will still need to fall back to oohembed.)

Warning: yfrog's own oembed responses do not include the thumbnail_width and 
thumbnail_height parameters, although the spec requires them if thumbnail_url 
is present.
