FYI: New Container test

FYI: New Container test

I added a new test for Container.addImpl. This shows that events are sent
to ContainerListeners even when the Container is not showing, and that
these events are delivered directly (and not via the EventQueue).

2005-11-02  Roman Kennke  <kennke@aicas.com>

        * gnu/testlet/java/awt/Container/addImpl.java: New test.
        * gnu/testlet/java/awt/Container/DisabledEventQueue: Auxiliary
        class for the above test.

This new test backs up a change that I made in Classpath recently.
