The Bill Paul clause to the BSD license

One of the lesser-known variants. I use "clause" here loosely; it's really in the disclaimer.

I'm attributing this to Bill Paul based solely on the frequency count in the FreeBSD source tree, though there are others. This sample is from 7.2-RELEASE:

 147 ENT SHALL Bill Paul OR THE
  28 ENT SHALL THE AUTHOR OR THE
  10 ENT SHALL NICK HIBMA OR THE
   9 ENT SHALL ICHIRO FUKUHARA OR THE
   1 ENT SHALL Ivan Sharov OR THE
   1 ENT SHALL David Hulton OR THE

The "THE AUTHOR OR THE VOICES IN HIS HEAD" instances are mostly in some ACL-related code, primarily by Chris Faulhaber. Hard to say which of these are cut-and-paste, and which are deliberate.

Either way, I'm using it from now on. :-)
