RubyGems on windows comes with a batch file that wraps the `gem` command
so it executes correctly. This change uses that batch file for windows
for our `gem` resource, and also properly handles when we receive no output
from the command.

Many of the resources are named as a top-level class with a fairly generic class name, such as "OS". This causes an issue specifically with kitchen-google which depends on a gem which depends on the "os" gem which itself defines an OS class with a different superclass. This prevents users from using TK, Google Compute, and Inspec without this fix.
Some mocked commands had their digest changed as well due to the new indentation, specifically in the User and RegistryKey classes.
I strongly recommend viewing this diff with `git diff --ignore-space-change`
to see the *real* changes. :)
