[PATCH 1/2] Documentation: Replace @@GIT_VERSION@@ in documentation

[Frank Lichtenheld <frank@lichtenheld.de>]

Include GIT-VERSION-FILE and replace @@GIT_VERSION@@ in
the HTML and XML asciidoc output. The documentation
doesn't depend on GIT-VERSION-FILE so it will not be
automatically rebuild if nothing else changed.
