Bug fixes:

        PreparedStatement.setObject didn't handle short's

        ResultSet.getDate() now handles null dates (returns null rather
        than a NullPointerException)

        ResultSetMetaData.getPrecision() now returns 0 for VARCHAR

New features:

        Field now caches the typename->oid in a Hashtable to speed things
        up. It removes the need for some unnecessary queries to the
        backend.

        PreparedStatement.toString() now returns the sql statement that
        it will send to the backend. Before it did nothing.

        DatabaseMetaData.getTypeInfo() now does something.
