* Make all docs depend on Makefile; if we change flags here we want them
rebuilt.
* Add explicit filenames to .gitignore so we can add our own CSS
override file, and add an asciidoc-override.css resource.
* Adjust a few asciidoc options when generating HTML.
* Remove asciidoc-manpage.css; apparantly this doesn't exist anymore.
