Version Control With Subversion Source

* www/index.en.html: Label nightly build as 1.4, not 1.3.

Be explicitly about externals definitions pointing at directories.

Suggested by: Eric Hanchrow <offby1@...>.

* src/en/book/ch-advanced-topics.xml
s/object/directory/ when talking about externals targets.

* src/tools/fo-stylesheet.xsl
* src/tools/html-stylesheet.xsl
Rearrange the order of some stuff in the stylesheets, because for
whatever reason it means the difference between a failed or a
successful built on my box.

Populate basic index entries for portions of the Reference chapter (it was
just too easy).

* src/tools/html-stylesheet.xsl
* src/tools/fo-stylesheet.xsl
Because I'm tired of looking this up repeatedly, put comments in the
stylesheets which point to the official HTML-rendered versions of the
parameter reference documentation.

* src/tools/fo-stylesheet.xsl
* src/tools/html-stylesheet.xsl
Add commented-out XSL parameters which enable auto-numbering of sections.

Ch08 translated into italian until svn.developer.webdav excluded.

* ru/book/ch07.xml: Two spelling typos have been fixed. Typos were found by Alex S. Kabakaev <ask2007@...>.

Fix some broken markup. An oops by C-Mike.

* src/en/book/ch-advanced-topics.xml
Lose an unnecessary summary paragraph.
