Add alpha variable to SpotlightViewController

[jstnheo]

Added alpha as a variable to SpotlightViewController making it more customizable.

 func presentAnnotation() {
        let viewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("Annotation") as! AnnotationViewController
        viewController.alpha = 0.5
        presentViewController(viewController, animated: true, completion: nil)
        annotationViewController = viewController
    }
