I have a module in which I have declared some friendly packages on the
Versioning page of an NBM module project properties dialog.

so..  there are a couple checked names in the Public packages list and there are
a  couple modules named in the Friends list.

I go an uncheck all the values in the public packages list and click the ok.

If I re-open the property dialog, the values that I unchecked have got their
check marks back.

After forcing the behavior implied by my actions directly on the project.xml
file, I see WHY the items became checked.  It would be a nice-to-have to get a
warning when the user pressed okay that would tell them: You told me to do
something stupid, and I am ignoring your wishes.
