Add a new encoder control, VP8E_SET_TUNING, to allow the application to inform the encoder that the material will benefit from certain tuning. Expose this control as the --tune option to vpxenc. The args helper is expanded to support enumerated arguments by name or value. Two tunings are provided by this patch, PSNR (default) and SSIM. Activity masking is made dependent on setting --tune=ssim, as the current implementation hurts speed (10%) and PSNR (2.7% avg, 10% peak) too much for it to be a default yet.
