Add Windows Support

[pento]

Also fixes #20.

Testing

Requirements:

• NodeJS LTS: https://nodejs.org/en/
• For Windows 10 Pro, Docker for Windows Stable channel: https://store.docker.com/editions/community/docker-ce-desktop-windows
• For Windows 10 Home, 8 and 7.1, Docker Toolbox: https://docs.docker.com/toolbox/toolbox_install_windows/
• A checkout of the WordPress repo: https://github.com/wordpress/wordpress-develop
• This PR. 🙂

Once it's all installed, open cmd.exe or PowerShell, cd to this PR, and run:

npm install In cmd: SET DEBUG=wpde:* In PowerShell: $env:DEBUG = "wpde:* npm start

In your Tray, click the WordPress logo, then the Settings gear icon. Select the wordpress-develop directory, then close your preferences, you should see debug messages continuing in your shell window.

The "Starting docker containers" step may take a little bit of time to run on a fresh install or slow internet connection, so don't worry if it just sits there for a while.

You should eventually see "WordPress ready at http://localhost:9999/". Please report the following:

• Do you see WordPress when you visit http://localhost:9999/ ?
• How long did it take to get from npm start, to WordPress being ready? (If it hung, make a guesstimate at how much time that was, too.)
• A copy of all of the debug messages output in your shell window.

I'm going to assume this works, and fix anything that comes up in bug reports.
