[Twisted-web] forms has been renamed to formal

Hi! I've just committed 3 changes to the forms SVN trunk that
change the package from "forms" to "formal", as agreed with Matt
earlier.

Now, I'd like to get a release done, and a debian package made
of it, then I can start using it for real. Matt, do you want to
handle the release or should I? What version number should it get?
