Documentation: Replace @@GIT_VERSION@@ in documentation

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.

[jc: fixing the case for interrupted build]
