FYI: Added test for JComponent.getPreferredSize()

I added a test for the JComponent.getPreferredSize() testsuite that
checks if it is possible to modify a JComponent's preferredSize setting
by modifying the returned Dimension object, or if this should be
protected.

        * gnu/testlet/javax/swing/JComponent/getPreferredSize.java:
        Added test for changing the value of preferred size.
