Title: Document function param required for `build` post 1.0.0.

Makes readme examples work with Metalsmith 1.0.0+ so that new users aren’t confused by silent build failures.

## Details
Adds the (now required) error handler param to the `build` call. Fixes #92 (also mentioned in #87). Note that if accepted, I suggest the same change be made to the examples on metalsmith.io.
