Updates to 2020/ferguson1

Updated chocolate-cake.md file with some added notes.

Added PDF file ioccc-and-chocolate.pdf which was downloaded from a
website I originally linked to in chocolate-cake.md.

Removed html files based on the markdown files as the markdown files are
the source of them and this is being done differently now. In other
words index.html and inventory.html have not been removed, just those
that were created by me (or from what I wrote).

This does not format fix anything as I can always do that later. It is
after all my entry.

Minor fix in play.sh.

Minor update in bugs.md.

I believe this completes the review of 2020/ferguson1 but it's entirely
possible (almost certain) that things could be cleaned up more. However
in order to get through the rest of 2020 I am only doing quick passes
over my entries.
