Fixes #2629: `Module::controllerPath` is now read only, and all controller classes must be namespaced under `Module::controllerNamespace`

This reverts commit 2bb6f135.

Fixes #2295: basic app description now doesn't insist it is for websites containing mainly informational pages since it was misleading

* Added 'return' to goHome() calls in actions
* Changed $_POST to Yii::$app->request->post()
