win_environment: Make this the Windows reference module

As discussed before we selected win_environment to the documentation,
and point to win_uri for a more advanced module.

If we want to make this the reference module, we have to get this one
absolutely right in every possible way.

This PR cleans up both win_environment and win_uri, and makes the
required changes to the windows module development section.

commit 31e7d735a3

@ -38,52 +38,17 @@ When creating a new module there are a few things to keep in mind:
- Use the full cmdlet name instead of aliases, e.g. ``Remove-Item`` over ``rm``
- Use named parameters with cmdlets, e.g. ``Remove-Item -Path C:\temp`` over ``Remove-Item C:\temp``
A very basic powershell module template can be found found below:
A very basic powershell module `win_environment <https://github.com/ansible/ansible/blob/devel/lib/ansible/modules/windows/win_environment.ps1>`_ is included below. It demonstrates how to implement check-mode and diff-support, and also shows a warning to the user when a specific condition is met.

A slightly more advanced module is `win_uri <https://github.com/ansible/ansible/blob/devel/lib/ansible/modules/windows/win_uri.ps1>`_ which additionally shows how to use different parameter types (bool, str, int, list, dict, path) and a selection of choices for parameters, how to fail a module and how to handle exceptions.
