Cakephp 2.7's FlashComponent requires flash elements to be in subdir Elements/Flash.

Needed to make e.g. the AuthComponent example with Cakephp 2.7

@slywalker please merge this

One small addition to this merge request. In order for this to properly work with Cake 2.7 the following should be added to the top of alert.ctp:

if (isset($params['class'])) {
    $class = $params['class'];
}

Usage example in Cake 2.7:

$this->Flash->alert('Alert message', [
  'plugin' => 'BoostCake',
  'params' => ['class' => 'alert-success'],
]);

Hi Slywalker, would you please merge these changes so that the plugin can be used with CakePHP >=3.0.0 and safely used with >=2.7?
