Allow using _index.md on no _index.gmi.md

Browse source 
This makes gmnhg use _index.md as directory / top-level index page
content source in case _index.gmi.md is not present.

As the renderer has matured a lot (namely lists of links are now handled
a lot better), this should allow writing almost zero content specific to
gmnhg.

The docs are updated accordingly.
