Consider running tests on Windows

The company I work for uses Windows, and we've been using ember-cli-addon-docs to document an internal addon. It is pretty evident that this code-base has not been run on Windows by the developers before. This is fair, but ultimately problematic. Ember-cli-addon-docs is increasingly used by addons across the ecosystem, essentially locking Windows users out of contributing to their documentation unless they are familiar with common issues and can debug/fix them.

We got it to work for us (although there are still rough edges), but I think this is something that will continue to break if Windows support is not part of every PR review. For this reason I propose running the test suite on Windows as well, for example using Appveyor. This is free for open source projects, just like Travis.

Please let me know what you think.

まず、リポジトリに既存のテストコマンドと CI 設定を確認し、次に Appveyor で Windows 上でテストスイートを実行する方法を調査します。Windows 環境でテストスイートを実行して、失敗や問題点を確認します。Windows でのテスト実行が PR の検証に含まれ、既存のテストがそこでパスすれば完了です。
