This gets rid of the hardcoded magic file names and allows more control for OS version, orientation, retina, and device.
But this existing code needs to be modified to look in the Info.plist for each key and act appropriately for the correct iOS version.
But iOS 8 superscedes this process and introduces the LaunchScreen NIB which uses autolayout to handle all orientations and devices.
Since we now have a LaunchScreen solution, this may never get fixed,
but this note is here for anybody trying to debug their program on iOS 7 and doesn't understand why their Info.plist isn't working.
