Please add support for the latest PhantomJS browser

[BrainSlugs83]

There is a 2.5 beta which supports ES6 (lots of pages that use stuff like 'Map' etc, don't work at all in the 2.0 stable -- 'causes some pages to not even load...) -- please add support for the 2.5 beta release.

You can find it at: https://bitbucket.org/ariya/phantomjs/downloads/

Note that just copying in the exe doesn't work, something in the protocol must have changed, so, if you want to support the 2.5 final release, you'll have to make that update anyway... :)
