Phantom test: Fix finding of submit button
phantomTest: Implemented test of login form

* Include jquery so we can use it to manipulate the page
* To assign values to text fields, Use .val() instead of .value =
* Use jquery to click on the submit button
* Add onUrlChanged notifier so we can observe redirects
* Phantom will exit after 3000 ms, so the login request has enough time to
complete

Output should look like this:
New URL: http://localhost:8088/page/site/login
finished
New URL: http://localhost:8088/page/site/unitTests
[end of output]
