(DOC-842) Confusing language around a code sample

This patch rewords the language around the code sample in the "On the
Command Line" section of the "Enable and Disable Puppet Agent" section
of the PE 3.x Orchestration documentation. It also adds a bit of
markup and the word "Example" to make it more consistent with other
examples on this page.
(DOC-847) Deployment Guide has inappropriate example

This patch removes an inappropriate and potentially offensive example
from the "How Can Puppet Enterprise Help You?" section of the
Deployment Guide.

(DOCUMENT-119) Add anchor links to section headings

This commit adds GitHub-esque anchor links to section titles as a
rollover effect. This will make it easier for people to figure out how
to link to a particular section in a given document.
Update stringify_facts description in list of important settings

Per PUP-2421, this is actually an agent-side setting and not a master
setting. Whoops.
Apply anchor links more conservatively

Adding them to ALL the headings caused some unfortunate side-effects in
the top header. This commit ensures that they'll only be applied to
H1-H4s within the #content section.
