[rygel] docs: librygel-server: Add sub-sections.

[Murray Cumming <murrayc src gnome org>]

commit 67ba798a1437696aa725b425ee4c839af12e3586
Author: Murray Cumming <murrayc murrayc com>
Date:   Wed Jan 16 13:10:05 2013 +0100

    docs: librygel-server: Add sub-sections.
    
    Move the chapter tags into the implementing-*.xml files,
    so we can have multiple sections in them. Give the chapters an ID
    so they can have meaningful URLs.
    Also link to the (unfinished) full rygel server plugin example.
