SWift 3 compatibility

[simplealina]

Hi there,

Thanks for the library. I've been trying all day to use it with Swift 3 but to no avail. The control does not display any of the items.

class BannerItem: NSObject, FPScrollingBannerItem {

    var bannerImage: UIImage!

    init(imageName: String) {

        self.bannerImage = UIImage(named: imageName)
    }

}

and:

scrollingBanner = FPScrollingBanner(frame: view.bounds)
        scrollingBanner.backgroundColor = UIColor.green()

        let arrayNames = ["paralaxtest_01", "paralaxtest_02","paralaxtest_03"]
        var arrayItems: [BannerItem] = []

        for name in arrayNames {
            let bannerItem: BannerItem = BannerItem(imageName: name)
            arrayItems.append(bannerItem)
        }

        scrollingBanner.delegate = self
        scrollingBanner.items = arrayItems

        view.addSubview(scrollingBanner)

All I can see in the end is the green background.
