RFC: Fixing handbook filenames (by id="blah" modifications).

[Tom Rhodes]

Greetings.

This morning, inspired by some unknown yearn to have the filenames
match the chapters (ie: s/nfs.html/network-nfs.html) I created a
patch that 'fixes' the advanced-networking chapter.

Since the handbook will not build if the <link> tags do not match
an id, the appropriate changes were made to the other chapters.

Before I commit this, does anyone have any opinions?  If this goes
in, I'll continue to work on this.  From what my builds show me,
this does NOT break anything.

Please see the semi large patch at:

for an idea of what my first commit would consist of.

Thanks!
