Fix the long-standing authz documentation bug regarding group permissions.
This was tracked in the book's issue tracker as issue #71. This commit
is based on the patch attached to that issue.

I also discussed this with striker (who wrote a lot of the initial authz
code) at the Apache Retreat. He confirmed that this was a documentation bug,
rather than a bug in the implementation.

* src/en/book/ch06-server-configuration.xml:
(svn.serverconfig.pathbasedauthz): Group permissions can only be
extended, not restricted, for individual group members. Document
this correctly, rather than claiming the opposite was true.
