Documentation: Rebuild index page

The index page already has sections, but I want to have a hierarchical index
rather than the current one.

I include a few new suggestions for topics that I believe are
missing from the docs today, mostly under End user guides and Server
administration.

The long term goal would be to rearrange the documents into folders
that correspond to the chapters suggested, and have this index auto-
generated by the build and put into a navbar that can be displayed on
all pages.
