build-page: support gopher pages
If second argument to 'build-page' is '-g' switch then gopher pages will
be built instead of html.
Gopher menus will add 'about' entries that link to 'index.md' if a
linked directory contains both 'index.md' and subdirectories. If
directory contains no subdirectories it will be treated as a link
directly to 'index.md'.
Current gopher page layout seems most reasonable to me. Links to domains
have to be somewhere as there is no 'homepage' before entering any
subdomains.
Makefile will still build only html pages by default as not to break
anything that is already in place. I also added an instruction for
gopher pages 'make gph' for manual testing and later integration
into default 'make'.
Added gph files to '.gitignore'.
