Update HISTORY and AUTHORS sections for cut(1) and paste(1)

In an e-mail Brian Walden wrote that:

"GWRL stands for Gottfried W. R. Luderer, the author of cut(1) and
paste(1), probably around 1978. Those came either from PWB or USG,
as he worked with, or for, Berkley Tague. Thus they made their way
into AT&T commercial UNIX, first into System III and the into System
V, and that's why they are missing from early BSD releases as they
didn't get into Research UNIX until the 8th Edition."

So update the HISTORY and AUTHORS sections for cut(1) and paste(1).
