This means dependency checking will work for SCSS as well. This may take more time than the quick-and-dirty regexp method, but I don't think there's a good way around it. Hopefully this will hit the cache most of the time. We could speed it up a little by storing the dependencies directly in the cache, or even more by keeping the dependencies in-memory.
