Adds missing static method to UIFont, that generates a UIFont with monospaced numeral rendering (which is disabled by default when linking against iOS 9 SDK - there you'll get proportional spaced numeral rendering).

FYI In Xcode 7 beta 4 I was able to get the same behavior as NSFont in the apple keynote
example: label.font = UIFont.monospacedDigitSystemFontOfSize(62, weight: UIFontWeightUltraLight)

Ah, you are right. They seem to have fixed this with beta 4! Great to know. 👍
