(PP-295) Add PUPPET_AGENT_ENVIRONMENT command line option

Adds the ability to specify the environment configuration setting on
Windows during installation, for example:

    msiexec /qn /i puppet.msi PUPPET_AGENT_ENVIRONMENT=dev
Use 100% for image max-width

This commit changes `max-width: 640px` to `max-width: 100%` for images in
the .primary-content container. This will give the images some additional
width when the viewport is wider than 940px. Also added a comment about
a misguided ally related style block.
(#17031) Adding domain users to local groups now works

As of 3.4.0, Puppet's windows group provider will support adding domain
users to local groups (as we already document). One side-effect of the new
implementation, is that you can specify either local or domain groups as
members of local groups, since group membership is expressed in terms of
SIDs, e.g. WinNT://<SID>.
Deprecate documentation for PuppetDB 1.3.x and 1.4.x

We have decided to deprecate all older branches now that PE has committed
to 1.5.x and no longer requires 1.3.x to stay open.

This patch pins the older revisions to tags I have created in puppetdb in the
form 1.1.x-docs so that we can close out the older branches for good.

It also puts up a deprecation message on the older 1.3.x and 1.4.x docs and
moves them into the older revisions area of the index.

As a bonus I've added a link to the master version of the documentation from
the index page, as we previously haven't provided that to our users.

Upgrading is only supported from latest point release

As per Nick Lewis, we only test upgrades from the "latest point release"
of each series.

E.g. upgrading from PE 3.0.0 -> 3.1.0 is *not* tested. Only upgrading from
3.0.1 -> 3.1.0 was tested. This is our standard practice.

It may work, but we should not claim that it does if we're not
explicitly testing it.
