Add all params of form values to execute

Problem/Motivation

We need to input some values when select items, not in confirmation step. And we alter vbo action form(views_form_[views_id]_[current-display]), but can't get these values when execute action.

Steps to reproduce

1. Implements hook_form_alter(), Alter some form elements for VBO.
2. I can't get form values when execute action.
