David Gröger 48ab5eb436 cli run-ios on device
Summary:
At the moment the run-ios command from the react-native cli does only work for simulators.
The pull request adds a new option to the existing command: **"--device 'device-name'" which installs and launches an iOS application on a connected device.**
This makes it easier to build a test environment using react-native for connected devices.

I've tested my code with the following commands:
react-native run-ios --device "Not existing device"
react-native run-ios --device
react-native run-ios --device "name-of-a-simulator"
react-native run-ios --device "name-of-connected-device"

Output of the first three commands:

Additional to the manual command tests i've added a test file 'parseIOSDevicesList-test.js'.

I used **ios-deploy** In order to launch and install the .app-bundle on a connected device.
