Support sourceMaps via {browserify: { debug: true }}

[naartjie]

Upgrade Browserify to new version, and hence allow SourceMaps when you pass {browserify: { debug: true }} option to the transform.

@naartjie What do you mean upgrade to the new version? I tried that locally and got no change.

Nevermind I did not actually upgrade, just derped.

@ericwooley This project seems kinda dormant and I haven't been using broccoli in a while now, and so I'm not up to date but your PR looks correct.

https://github.com/eploko/broccoli-watchify as of 1.0.0 supports this.
