Title: greyscaling unearned badges

quasi-greyscaling of unearned badges, using opacity mixing between the image, a dark blank template overlay, and the combination of the two.

We can tweak these values to make it look a little better, but we're not going to get it to a point that is true grayscaling until either:

1) Firefox and Opera support the CSS3 "filter" property properly
2) we add in "unearned" graphics building when badge images are saved for a badge at the (cl)openbadge(r|s) backend
