Title: Convert to idiomatic-gulp approach

The plugin now returns a single stream instead of two streams.

This fixes two problems:

1. Now the output can be piped into other plugins.
2. In the previous technique gulp can never tell if the task has
actually completed because it doesn't have a stream to test.
