Native code in vm/ can now be built using Xcode5 and the iOS 7 SDK. Dropped support for building against iOS 5.x. (#144)
Fixed so that apps will link with Xcode5 and iOS 7. Had to change -miphoneos-version-min=3.0 to -miphoneos-version-min=5.0 when linking. (#144)
Will now use icudt51l.dat (iOS 7) if available. (#81) (#144)
