Title: add option to show subtitle if only one marker is in a cluster

`MKAnnotation` as a `subtitle` property which is useful for showing things like street addresses etc.

This small patch adds the (optional) ability to show the subtitle using REMarker/RECluster objects.
The subtitle will only be shown for single item clusters. Theoretically a option could be added to show a subtitle for clustered markers as well.
