Make use of CompassFilter::setNoLineComments to turn off comments in compiled css

I'm not sure if there is a way to do this that I'm missing but i spun my wheels for a good bit trying different settings in config.yml and parameters.yml to turn off the debug comment output for CompassFilter. I finally took a look at the bundle and realized the parameter wasn't set up.

If this is already supported in some other way please let me know.
