Use full import for Cache Facade instead of alias

[iamrgroot]

Is there a specific reason to use the alias in stead of the full Facade import for the caching?

I came across a project that doesn't have the Alias in config/app.php and laravel-settings crashes because it uses the alias. My suggestion would be to use the full path:

Now:

use Cache;

Full import:

use Illuminate\Support\Facades\Cache;

Not a reason, I would merge such a PR!
