Adds the ability to choose between iPhone or iPad (low and retina) simulators when working with a universal app

[j-mutter]

When using Zucchini with Universal apps, the simulator always runs as an iPad. This adds support for specifying which device, and at what resolution, the simulator should use when running a test.

Usage

Simply specify a 'simfamily' value in your config.yml file for your iOS Simulator device - either iPhone or iPad

  iOS Simulator: 
    screen: low_ios5
    simfamily: iPhone

Screen resolution is determined by the screen value, in this case, low.

I don't think a framework should mess with iOS app internals.
Can you make this into a third party utility that can be chained with zucchini on the command line?
