Bug in system browser

Hi Andy and Blair,

I found a bug in the system browser. This is in a clean 5.01 Pro image.

If you try to create a new class in an empty package, then you don't have a
superclass to navigate from. This opens a DNU dialog: ContainerView does not
understand #selectionOrNil:

You can reproduce it with the following steps:

In the system browser, select a package with no classes in.
Select the 'new class' button.
Enter a class name.
The superclass field is still empty.
Press the superclass button.
