Enable PhantomJS for running Selenium tests

Browse Source 
This patch enables the PhantomJS webdriver for running
the Selenium test suite.

Use it with the --selenium-phantomjs command-line switch
when executing the selenium and integration suite.

If you can't run a virtual display, or would prefer not to, you can use the
PhantomJS web driver instead:
$ ./run_tests.sh --with-selenium --selenium-phantomjs
If you need to install PhantomJS, you may do so with `npm` like this:
$ npm -g install phantomjs
