  -----------
  Improve formatting. (#542)

* Improve formatting.

Especially, the section headers have been bumped, as they certainly
are no subsection of the preceeding "Controlling Base HREF".

modified:   docs/zdgbook/ObjectPublishing.rst

* Restructure document layout / hierarchy

Thanks to @dataflake for the suggestion:

"The main headers should be...

- Introduction
- HTTP Publishing
- Other Network Protocols
- Summary

Everything in between is second level"
