Inform6 extensions for the Unix tarball

In my efforts to refresh the Unix tarball of Inform6, some significant issues have come up regarding the extensions and if it’s okay to redistribute them. Many extensions were removed because they were vague on that subject or didn’t declare a license at all. I would like for everyone who has written an Inform6 extension to please declare a license for your code. The Artistic License 2.0 seems most inline with “do what you want with it” but still have your name attached to it. Declaring it public domain is great too. Please feel free to ask any questions about this.
