Convert Model Exception to Runtime Exception

Sometimes the exception thrown by the database providers has to be
converted to a runtime exception, especiall if the database provider is
running in a thread (called by the rum() method that does not return
exceptions). It is convenient to have a constructor on the
PfModelRuntimeException class that takes a PfModelException class as its
argument, thus creating the runtime exception.

Also the mapMap method in pfUtils is updated to allow the key of the map
to be templated. By doing this, the utility can be used for maps that
are keyed with types other than String (such as UUID).
