Version Control With Subversion Source

Remove from COMMITTERS (and the auth system) English users who got
grandfathered commit access by virtue of having full commit access on
the Subversion repository at the time the book was split off from it,
but who've never committed to the book sources:

jimb Jim Blandy <jimb@...>
gstein Greg Stein <gstein@...>
daniel Daniel Stenberg <daniel@...>
kevin Kevin Pilch-Bisson <kevin@...>
philip Philip Martin <philip@...>
jerenkrantz Justin Erenkrantz <justin@...>
bcollins Ben Collins <bcollins@...>
epg Eric Gillespie <epg@...>
jszakmeister John Szakmeister <john@...>
dberlin Daniel Berlin <dberlin@...>

I'd trust any of these folks to tweak the book, of course, but would
prefer that we avoid spurious accounts.

Remove fa_stu and giorgio_valoti usernames, at Federico's request.
