Simple validation to check if the field is a file

[asanikovich]

Laravel dosn't have validation rule to check if the field is a file (not image or specific mime type):
I resolved this by:

Validator::extend('file', function($attribute, $value, $parameters) {
    return \Request::hasFile($attribute);
}, trans('validation.file'));

In \resources\lang\en\validation.php

'file'                  => 'The :attribute must be a file.',

You should add it to the docs.
