(Selective Versioning): Remove unnecessary word "currently",
suggested by Ben.

phrase "configuration area", for clarity. Patch by
Eric Hanchrow <offby1@...>

Ben's fixing-up of the Preface, for our Jan. 5 deadline.

* book.xml: update copyright, and also say it's a 1.4 book, not 1.3.
(My understanding is that we're upgrading the book to
cover both 1.3 and 1.4 at a minimum, right? Possibly even 1.5
if it gets finished in the next few months?)

* ch-preface.xml

- add two new starting quotes we can choose from.

- rephrase intro to make CVS sound like it "used" to be the
big standard, but no more. :-)

- Do NOT recommend cygwin to windows users.

- Remove mention of CVS from a number of places, so we stop
sounding like we're constantly migrating CVS users.

- Fix some brokenness in the list of chapter descriptions.

- Add some more names to our huge acknowledgement list.

- Update my own 'thank yous'.

- List svnsync as an installed component.

- Lots of cleanup and rephrasings here and there.

Branch: ora-2e-reorg

Finish my first pass over Chapter 3. If I had to turn this chapter in
to Tatiana today, I'd be comfortable doing so.

* src/en/book/ch-advanced-topics.xml
(Locking, Externals Definitions): Tweaky, tweaky...
