http.createClient in utils.js produces a deprecation warning

Hi,

I don't know for how long createClient would be available in node but it would be great if someone can get rid of this call and switch to http.request. I don't trust myself to the task...

Thanks

Start in utils.js and locate the http.createClient call. Replace that deprecated call with http.request, then run the existing nodeunit test suite and confirm the deprecation warning is gone without changing the expected behavior.
