This will render about pages using the Comrak renderer defined in
Cheddar.
Note that due to the way its implemented this will have one
interesting behaviour: Markdown files in the tree will *also* be
rendered as HTML.
I will need to see how that works out before deciding whether or not
to disable it.
This moves the various projects from "type-based" folders (such as
"services" or "tools") into more appropriate semantic folders (such as
"nix", "ops" or "web").
Deprecated projects (nixcon-demo & gotest) which only existed for
testing/demonstration purposes have been removed.
(Note: *all* builds are broken with this commit)
