Feature description

In attempting to connect a debugger to the integration tests

node --inspect-brk node_modules/.bin/gulp integrationtest

I discovered that the gulpfile spawns a subprocess, and in doing so drops the --inspect-brk flag.

I have found my temp workaround

   // passed to the Node.js process itself and not to the script that it runs.
+  args.unshift("--inspect-brk")
   args.unshift("--max-http-header-size=80000");
   return spawn("node", args, options);
 }

to be quite useful in allowing me to step through the automated user interactions and observe the expected behavior of the app. It would be nice if this was configurable on the command line.
