Flipped Images Logic

Upon creation of a grading set, a percentage flipped images is assigned (10% by default) - store this number so changing it in the future doesn't un-finish grading sets.

Derived # for grading set:

flipped_image_count = Math.ceil(image_count * flipped_percent) 

Total number to grade is # of images + (# of images * flipped percentage)

Create a second phase of grading - flipped grading:

1. Do the number of flipped user_grading_set_images equal or exceed flipped_image_count for the grading_set? If not, continue.
2. Pick a grading_set_image at random. If already a flipped image, pick another.
3. Present that image for grading.
