Generified ResultSetIterator.

The class now implements Iterator<DynaBean>. This is a source-incompatible
change as the return value of a method changes. Maybe it has to be discussed
again whether such a change is allowed. The alternative, implementing
Iterator<Object>, would not be very satisfying though.
