Adding new names for exiting packages

[Kent M. Pitman <kmp at MIT-AI>]

It would be useful to have a function which would add an additional 
refname to a package after the package has been created. I have written
such a function myself, but since it has to call accessors which are
really internal to the system, it is more rightly maintained by the
system implementors. The function as I wrote it is PKG-ADD-REFNAME and 
lives in AI: KMP; PKGADD > if you want to pick it up and look at it.
