Huxley fails to take a screenshot

[alitheg]

I've just downloaded Huxley on Windows 8.1, and added a Huxleyfile to my project. After some tussling with Firefox and Selenium versions, I finally got Huxley to launch a browser. However, when I go back to the command line and hit Enter to take a screenshot, Huxley crashes with the following error:

The crash seems to be fixed by changing this:

  screenshot_step = ScreenshotTestStep(d.execute_script('return Date.now();') - start_time, run, len(steps))

to this:

  screenshot_step = ScreenshotTestStep(d.execute_script('return Date.now().getTime();') - start_time, run, len(steps))
