Conpherence - add crop

Summary:
mainly, this adds the image cropper - yay!

 - also removes the file image from the handle stuff I added in V1. now we do all this crazy photo stuff.

Test Plan:
 - uploaded a photo by dragging to header and noted 120 x 80 showed up on reload
 - uploaded a photo by dragging to edit dialogue spot and noted 120 x 80 showed up on reload
 - cropped a photo - noted it cropped right
 - cropped a photo again and again and again - seems like it crops okay
