Fixed #7. The alert appeared behind the keyboard.

Made keyWindow public so users can set their own parent view. This allows anyone to apply keyboard constraints as they want to.

An example how a user could use this;

import UIKit
import SPAlert

class ViewController: UIViewController {

    @IBOutlet weak var inputField: UITextField!

    @IBOutlet weak var wrapperView: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()

        // attachKeyboardConstraint()

        inputField.becomeFirstResponder()
    }

    @IBAction func textField(_ sender: Any) {
        let alertView = SPAlertView(title: "Added to Library", message: nil, preset: SPAlertPreset.done)
        alertView.keyWindow = wrapperView
        alertView.present()
    }

}
