Re-pointed the js test runner (chutzpah) to run tests directly from the booted IIS server.

- AKA instead of pointing the runner to a file location we now point it to http://localhost:1337/.  This allows tests to run in a "true" same domain environment instead of an emulated one.
- I left the JS code used to re-point the tests to a server in-tact in-case we want to create a true cross-domain testing scenario.
