Deprecate setBackgroundColor from UIButtonExtensions

[lfarah]

This method is useless since UIButton.backgroundColor = .black exists since iOS 8.

extension UIButton {
    public func setBackgroundColor(_ color: UIColor, forState: UIControlState) {
        UIGraphicsBeginImageContext(CGSize(width: 1, height: 1))
        UIGraphicsGetCurrentContext()?.setFillColor(color.cgColor)
        UIGraphicsGetCurrentContext()?.fill(CGRect(x: 0, y: 0, width: 1, height: 1))
        let colorImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        self.setBackgroundImage(colorImage, for: forState)
    }
}

I okay it's inherited from UIView.

But what if I want different different colors for different states?

Especially I faced this method when I had one color for the button, and that color but with less alpha for highlight state.

Hmmmmm totally makes sense!

Wait, lets not disregard this yet. There might be a better way to achieve this with shorter code in new swift. I'm not sure how but lets think about it.

Lets try to solve this without using UIGraphicsImageContext
