Compiled PHP for customized route matching

The second parameter of `rtrim()` is a character mask. By checking if `rtrim($pathinfo, '/contact') === ''`, `$pathinfo` could be any URL containing those characters and not only "/contact" which was configured as the route path, for example:

    $pathinfo = '/octocat';
    var_dump(rtrim($pathinfo, '/contact') === ''); // bool(true)
it should be: ` if (0 === strpos($pathinfo, '/_profiler')` (since this example is just copied verbatim from the generated cache file)
