Find a way to show index.html raw files that get overriden by directory listings

Edit: first implemented the _index thing. But actually noticed would be saner with a separate _dir/ prefix for directories. Otherwise a recursive wget/zip would not work out of box which makes me sad. It is a bit sad that you can't just remove a path from _raw/path/to/file.txt to go to _raw/path/to/ as you need _dir/path/to/ instead. But so bet it.

E.g. subdir/index.html which would show up under _raw/subdir/index.html gets overriden by the directory listing of subdir/ which goes to the same location.

One possibility would be to add an underscore: _raw/subdir/_index.html for the file. And another underscore for _index.html and so on.
