+- Changed behavior of controller name extractor. Now it uses greedy search of namespace items with "controller(s)" 
+  postfix. For example, controller namespace is `App\AllControllers\MyController\FooBar\BazController`. Previously,
+  result was "controller/foo-bar/baz", now it is "foo-bar/baz". You can use `ViewRenderer::withControllerName()`
+  instead of `ViewRenderer::withController()` to explicitly define controller name.
