Compute interestingness as ratio of R,G,B #17

Use the ratio (R+G)/2 / B to try and discriminate images which are "only blue" from those that contain other things as well.

Want to keep pictures that show 90% ocean and 10% coast and such. Also we compute this from the preview images which are not colour adjusted etc.

This has been deployed for a few days now but forgotten on my laptop.
