Issue with browserify

[Kyos]

What's this PR purpose?

When you try to browserify a file which require when, you get this error :

Error: Cannot find module '../when' from '/Users/olivierlaniesse/src/iadvize/test/node_modules/when/dist/browser'
    at /Users/olivierlaniesse/src/iadvize/test/node_modules/browserify/node_modules/resolve/lib/async.js:55:21
