            <description>

                Added interface <code>J2SECustomPropertySaver</code> with method <code>save()</code>

                to enable correct saving of properties added by JSE Project extending modules.

                If a JSE Project extending module adds/modifies panels in Project Property

                panels, then a mechanism is needed to ensure that all user-modified properties

                are correctly stored in project.properties and private.properties when OK pressed.

            </description>
