By using [node-which](https://github.com/isaacs/node-which)
I believe I am able to get rid of the `php` command running
`php-cs-fixer` as an argument.
`which` will find the `php-cs-fixer` program by looking through
the `PATH` environment variable listed directories.
This will resolve `php-cs-fixer` to an absolute path to the executable
and that will be used to run the command.
This dramatically cleans up the `PHP-CS-Fixer beautifier` code and specs, too!
Doing some Windows tests now.
