Add Helper Methods to Controller

Commonly used return behaviors should be factored out into helper methods which can be called, like:

function edit($id) { $model = Make::a('Model'); $model->id = $id; return $this->findOr404($model); }

Other interesting ones would be: return $this->ok(); return $this->insertOrSendBackTo($model, 'fail-view'); return $this->redirect('another/url');
