Title: Avoid showing the user multiple rating alerts

We've had an annoying issue where appirater would sometimes show the user multiple alert dialogs. I have fixed this by maintaining a weak reference to the `UIAlertView` dialog and refusing to present if the reference is non-nil. I also dropped the interval ivar since it looked most properties were auto-synthesized and Xcode was showing a warning.
