[a11y guide] Desktop Appearance Enhancement section misplaced

[Luca Ferretti <elle uca libero it>]

The "Desktop Appearance Enhancement" section (id=themes-0) in
gnome2-accessibility guide is currently placed inside Orca section. I
think it should be (and I've memories it was) nested in pair with Orca
section, as listed in "Low Vision or Blindness" intro.

In short "Desktop Appearance Enhancement" section is currently numbered
as 3.1.9, while it should appear as 3.2

Attached the trivial patch to fix thi (just move around a </section>).
OK to commit?

PS I'm referring to trunk, I didn't checked stable branch
