Validation doesn't function if the Input facade isn't aliased

[Gawdl3y]

If an application doesn't have the Input facade alias, the package's input validation will fail with an exception, due to the "Input" class not being resolvable in the IoC. Reliance upon a facade/alias is probably a bad idea for a package, since there's no guarantee they'll be present. Furthermore, Laravel 5.2's default config no longer includes the Input alias (see laravel/laravel@2adbbbd).
