/**
* Perform alterations on the VBO form before it is rendered.
*
* Usually, if a module wanted to alter the VBO form through hook_form_alter(),
* it would need to duplicate the views form checks from
* views_bulk_operations_form_alter(), while making sure that the hook
* runs after VBO's hook (by increasing the weight of the altering module's
* system entry). In order to reduce that complexity, VBO provides this hook.
*
* @param $form
* A step of the VBO form to be altered.
* @param $form_state
* Form state. Contains the name of the current step in $form_state['step'].
* @param $vbo
* The VBO views field. Contains a reference to the view in $vbo->view.
