Adopt Laravel coding style

Shift automatically applies the Laravel coding style - which uses the PSR-2 coding style as a base with some minor additions.

You may customize the adopted coding style by adding your own [PHP CS Fixer][1] `.php_cs` config file to your project root. Feel free to use [Shift's Laravel ruleset][2] to help you get started.
