Update to “Controller Filters ”

URI multi-level directory will be prompted wrong.
err mes : preg_match(): Unknown modifier 'r'

show demo:
application/Config/Filters.php
public filters = [
    'foo' => ['before' => ['admin/foo/*']],
    'bar' => ['before' => ['admin/bar/*']]
];

 If the delimiter appears often inside the pattern, it is a good idea to choose another delimiter in order to increase readability.
