Version Control With Subversion Source

For issue 178 ("document ephemeral txnprops (new in 1.8) and how hook
scripts might use them."), document the ephemeral transaction
properties in the property reference section. We still need to give
examples of their utility.

* en/book/ch03-advanced-topics.xml
(svn.advanced.props.ref.ephemeral): New section.

Finish issue 176 ("'start-commit' hook script changed in Subversion
1.8.").

* en/book/ch04-branching-and-merging.xml
(svn.branchmerge.advanced.hook-ex1): Update start-commit hook
example.

* en/book/ref-reposhooks.xml
(svn.ref.reposhooks.start-commit): Update start-commit hook
reference material.

Fix issue 169 ("In Subversion 1.8, the --accept option to 'svn
resolve' is optional.").

* en/book/ch02-basic-usage.xml,
* en/book/ref-svn.xml
Rework bits of text to no longer imply that 'svn resolve' requires
the --accept option.

* en/book/book.xml

* COMMITTERS
Remove. Access control for the project is managed (publicly) at
svnbook.googlecode.com, and nearly all of the translator information
is beyond stale.

* tools/base-html-stylesheet.xsl
Don't set TOC configuration parameters here, hoping to override them
in chunk-stylesheet.xsl. That's not how XSL works.

* tools/chunk-stylesheet.xsl,
* tools/html-stylesheet.xsl
Rather, declare them here for the two different HTML output flavors.

* en/book/ref-reposhooks.xml
Wrap synopses with <literal> for consistencies with other references.

* en/book/ref-svn.xml
Merge the "global" and "not-so-global" options lists together, using
<note>'s to call out the options which are universally supported.
Add a title to the single <variablelist> so that it can be
crossreferenced cleanly.

* en/book/ref-svnadmin.xml,
* en/book/ref-svndumpfilter.xml,
* en/book/ref-svnlook.xml,
* en/book/ref-svnrdump.xml,
* en/book/ref-svnsync.xml
Give titles and IDs to the options lists here, too.

* en/book/styles.css
Style magic to make these named variable lists' titles stand out.
