Title: Add Environment Variable for each GV Variable

In a recent Pull Request (#262), the decision was taken to, in the absence of setParameter being available in AppVeyor, to create environment variables that could then be accessible in the remainder of Build Script. I would like to suggest that this also makes sense for TeamCity.

In my scenario, I want to use:

```/output buildserver```

but use the generated variables later in my psake build script. In order to do this, I have to call GitVersion twice.

Using this approach should mean that I can access the created Environment Variables later in my psake script when I need them.

Does that make sense?
