Fix missing css output when cssDir == sassDir.

Without this, I wasn’t seeing any compiled CSS in my broccoli output.
Update per PR suggestion
Another tweak.
Use new version of broccoli-caching-writer.

This version includes support for caching to filesystems that do not support symlinking, which is a problem that occurs when using shares on Virtualbox and VMWare Fusion.
Revert version bump.
