General iOS7 fixes
-updated example project for Xcode 5
-page dots (UIPageControl) now same height as status bar. This is about 5px bigger than what it was before and cuts into the content area, so if your content for each page depends on being an exact size you may want to be aware of this.
-Improved for iOS7 - added an extra new property "hideStatusBarWhenScrolling" intended for iOS7+ to account for the fact iOS7+ status bar now overlaps the app's view. To use it you must set the "UIViewControllerBasedStatusBarAppearance" key in the info.plist to NO. See documentation.
-Changed example project to set the "hideStatusBarWhenScrolling" property to YES when using iOS7+
