Annotate delegate methods as `nullable` #19

The method - (UIImage *)pageControl:(FXPageControl *)pageControl imageForDotAtIndex:(NSInteger)index should be nullable, so we can easily change a single image and keep the rest with the default.

As it is now, it's all or nothing, even though the code manages this case properly and falls back to the default image.
