This class is meant to be used with your Github hosted WordPress plugins. The purpose of the class is to allow your WordPress plugin to be updated whenever you push out a new version of your plugin; similarly to the experience users know and love with the WordPress.org plugin repository.
Made the regex a little smarter, so it will read different notations of the version in plugin headers as well.
Closes #62 as well, skip reading the readme file if there is already a version found.
