Change current working directory

[henrytseng]

Is it possible to change the current working directory? Maybe something for example like where the application runs relative to api2/index.js:

gulp.task('serve', function(callback) {
  server.listen( {
    cwd: 'api2/',
    env: {
      NODE_ENV: 'development',
      DEBUG_COLORS: 1
    },
    path: 'index.js'
  }, callback);
});

Hmmm, didn't read the source code before I wrote this. Maybe document? I'll throw out a pull request.
