Image Cropper with Rotation

[johnklucinec]

I noticed the image croppers don't seem to have a way to rotate the image. I was thinking it would be useful if this could be added as an optional feature. It doesn't have to be anything complex, just a simple button that turns the image 90 degrees at a time would be really helpful. I think this might be possible using a element.

I will probably implement this feature myself for now, but I like the look and feel of your end products.
