In an effort to make upgrading the constantly changing config files
easier, Shift defaulted them and merged your true customizations -
where ENV variables may not be used.
* Shift core files
* Shift app folder structure
Laravel 5.3 no longer includes the `Events`, `Jobs`, `Listeners`, and
`Policies` folders by default. Instead, they are created when you make
them using `artisan`.
* Shift Middleware
* Shift Providers
* Shift configuration
* Shift Routes
Laravel 5.3 now stores Routes in a top-level `routes` folder and
separates them into API, console, and web files.
* Shift deprecations
The `Str::randomBytes` and `Str::equals` methods were deprecated in
Laravel 5.2 and removed in Laravel 5.3 in favor of the native
`random_bytes` and `hash_equals` PHP functions.
In addition, the Collection method `lists()` was replaced with
`pluck()`.
* Shift Laravel dependencies
* Shift cleanup
* Updated composer.json
* Updated providers to 5.3 style
* Removed events folder and extend correct exceptions handler
* Updated configuration
* Shift back our method names from ending in "pluck" to "list"
* Temporarily add back in old mcrypt encrypter
