Add Tune for SSIM

Implementation with some tuning of the paper:
C. Yeo, H. L. Tan, and Y. H. Tan, "On rate distortion optimization using
SSIM," Circuits and Systems for Video Technology, IEEE Transactions on,
vol. 23, no. 7, pp. 1170-1181, 2013.

Test results:
           avg_psnr      ssim      ms-ssim
lowres      2.516       -2.622     -2.450
midres      2.312       -3.062     -3.882
hdres       2.292       -4.293     -5.246

The encoding time is about the same as the baseline.
