Selection: provide convenience function for single-dive selection

Browse source 
Currently, selecting a single dive or deselecting all dives was
quite awkward: One had to pass in a single-dive vector and the
dive itself (as current dive). Provide a convenience function
that selects a single dive or deselects all dives if null is
passed in.
