Re-attribute a substantial chunk of docs, due to lost original author

The mysterious <g> is seen on the channel between Aug 24 and Sep 3 of 2008
talking to castaway and various other hackers, supplying a number of doc
patches and then vanishes. Due to the need of correct authorship imposed
by the next commit, reattribute the docs to castaway instead

This is the only such instance - all other authors have been accounted for.
Deemed acceptable as the name is entirely and utterly lost in the ether :(
