Change how example remarks is managed

The file next/remarks.example.md has been renamed next/remarks.md.

From this file a new html file, next/remarks.html, is generated. The
first part of the instructions say to download the markdown file and
copy it to your submission's directory.

The rest is mostly the same but this way one can look at the website and
also be aware of the file (and it'll be linked to in the rules and/or
guidelines as well).

This required updating bin/gen-top-html.sh an bin/md2html.cfg and the
Makefile was updated too (with a typo fix also).
