Using all UIViewAnimationOptions as UIViewKeyframeAnimationOptions

UIViewKeyframeAnimationOptionsExtension.swift

// This enables using all available UIViewAnimationOptions enum values as UIViewAnimationOptions in a Swifty way,
// by brute-force bridging all values with an explicit extension to UIViewKeyframeAnimationOptions.
//
// Thus, code like
// 
// let o1 : UIViewKeyframeAnimationOptions = .CalculationModeLinear
// let o2 : UIViewAnimationOptions = .CurveLinear
// let os : UIViewKeyframeAnimationOptions = [o1, UIViewKeyframeAnimationOptions(o2.rawValue)]
// 
// becomes:
// 
// let os : UIViewKeyframeAnimationOptions = [.CalculationModeLinear, .CurveLinear]
