[Rd] Same class name, different package

In principle, two separately developed packages could use the same class name, and a user could then attach both and attempt to use methods for both classes.

That has never worked, but some changes have been added to r-devel to handle this case. The changes involve extending the "signature" class to include package information. For compatibility, packages will need to be re-installed from a version of R labelled 56466 or later, although an attempt is made to fill in missing information.
