Redwood: Contributing on Windows isn't currently possible

[weaversam8]

Hey guys. As you know (by now) I'm a Windows user.

The instructions provided in CONTRIBUTING.md don't work on Windows, since build scripts take advantage of Linux shell specifics.

For example, rm is not a valid command on Windows, and prefixing scripts with NODE_ENV=production doesn't work, since that's not how environment variables work on Windows.

To achieve a platform-agnostic build process, I've seen packages use packages like win-node-env and rimraf to replace these commands.

Ah, @weaversam8 we had no idea! A frustrating issue indeed and appreciate you reporting it -- we need all the help we can get 😃

Could you take this PR for a local test run and let me know how it goes? #363

[weaversam8]

Yep! I'll take a look at this probably sometime before the end of the week!

Sorry this took so long, but I just added some feedback over on the PR.
