Version Control With Subversion Source

For issue 5 ("Document svnmucc"), begin fleshing out the reference
material for svnmucc.

* en/book/ch09-reference.xml
(svn.ref.svnmucc): Document svnmucc's Actions and Options in new
subsections of this section. Leave a placeholder section for
Examples, too.

* en/book/ch03-advanced-topics.xml
(svn.advanced.working-without-a-wc.svnmucc): Point out that svnmucc
can make all the changes that svn can make. Add a warning box
about the need for specifying a base revision, and update examples
to show that being done.
