We plan to move the concepts from designs.a.o to the website. To lay the
foundations for this move, move documentation that was on the old wiki and
referenced from designs.a.o into `concepts/`. As these were referenced by
the designs, take them to be of equal importance to that information.

Add an index page that briefly describes what the concepts constitute,
basically topics that have been researched but not necessarily
implemented. Fix up any links that pointed to the location of the old
"concept designs".

There are a number of broken links on the website that can be replaced with
updated links pointing to the relevant information. Where this is not
possible reword documents to not rely on the links rather than having
broken links.

The wiki markup made it so that fragment links needed to be named as per
the link name, thus enforcing the link test for such URLs started with a
hash. As we are not using a wiki anymore, this is not the case and we can
clean out the hashes to make the text more readable.

There are a number of badly formatted links that don't point correctly to
resources or point to resources that aren't available. Where possible
correct the links, if this is not possible remove or neuter the link to
preserve as much as possible.

A number of files in the `content/` directory are either unlinked (and
therefore hidden) or would have contained a message (generated by a wiki
template) stating they were obsolete and pointing to the updated location.

 - Move the unlinked documents into guidelines so that they are at least
   accessible via the automatic list, link if a quick location can be
   found.
 - Remove the obsolete pages and update the links to point to the correct
   location.

A number of documents used to be marked as work in progress on the wiki.
Move these to their own folder to make this distinction.
