Identify libsass-friendly libraries

[dylang]

It would be helpful to label resources that work with libsass.

This might mean everything that doesn't require Compass, so an alternative way to solve this is to label which ones require Compass or Ruby.

I think this is an awesome idea, will work on adding support for this feature.

@jhardy Do you think this should be another line in the sache.json file? Whats your initial thought on how to flag these?

[jhardy]

@hatefulcrawdad yeah, we can make it a part of the json file.

FWIW, in the npm world this goes in the peerDependencies section of the package.json, but I don't know if sass library authors know that or realize that it's helpful to include a package.json with their code.
