A set of annotation delegate callbacks for JCTiledScrollViewDelegate

I did a more complete set of delegate callbacks :

    -(void)tiledScrollView:(JCTiledScrollView *)scrollView annotationWillDisappear:(id)annotation;
    -(void)tiledScrollView:(JCTiledScrollView *)scrollView annotationDidDisappear:(id)annotation;

    -(void)tiledScrollView:(JCTiledScrollView *)scrollView annotationWillAppear:(id)annotation;
    -(void)tiledScrollView:(JCTiledScrollView *)scrollView annotationDidAppear:(id)annotation;

    -(void)tiledScrollView:(JCTiledScrollView *)scrollView didSelectAnnotationView:(JCAnnotationView *)view;
    -(void)tiledScrollView:(JCTiledScrollView *)scrollView didDeselectAnnotationView:(JCAnnotationView *)view;
