Subject: Enable HTTP Verb in Routing

Using array for HTTP Verb

e.g:
$route['(:any)']['POST'] = "controller/post_method";
$route['path']['GET'] = "controller/path_get_method";
$route['path']['(:any)'] = "controller/path_any_method";

Using (:any) or not will make same result
e.g: $route['path']['(:any)'] == $route['path']

So it won't break existing route
