No love for cocoa relative formatting

[redent]

In Swift 1.2 we had a parameter in toString method to enable doesRelativeDateFormatting flag in NSDateFormatter. That parameter is now gone and there's only one method to enable it:

public func toRelativeCocoaString() -> String? {
    let formatter = NSDateFormatter()
    formatter.locale = region.locale
    formatter.calendar = region.calendar
    formatter.timeZone = region.timeZone
    formatter.dateStyle = .MediumStyle
    formatter.doesRelativeDateFormatting = true
    return formatter.stringFromDate(UTCDate)
}

However this method forces dateStyle and timeStyle and create a new NSDateFormatter on each call. In addition. NSDateFormatter.cachedFormatter() is declared internal, so no other DateInRegion extensions can use it.
