detect phantomjs in grunt reporter

[tkellen]

this is handy if you want to run your specs in a normal browser (since the fix for issue #4 seems to be inlining this script on your runner)

Hi @tkellen I was just going to review this right now, but noticed you'd closed the pull request. Wasn't it working correctly?

Hey Camille!

I'm using this over on tkellen/requirejs-library-skeleton (and all the libraries I've built with the template). For whatever reason, the issue with the tests timing out (creynders/grunt-jasmine-task#4) resolved itself so it wasn't needed.

This is what I did, if you'd like to include it:

if(/phantom/i.test(navigator.userAgent)) {
    jasmine.getEnv().addReporter( new GruntReporter() );
}
