Title: Handle errors using metalsmith pipeline

Handle errors as told here:
http://www.robinthrift.com/posts/metalsmith-part-3-refining-our-tools/#a-note-error-handling

Doing that, metalsmith's `build(function(err, files) {})` can handle it.

Currently if a scss file fails building, it is impossible to catch it through metalsmith pipeline.
