function layout_ajax_form_save_dialog

AJAX handler that saves a form in a dialog and updates the underlying form.

This is meant for generic use. It depends on a few variables in $form_state:

• $form_state['ajax_rebuild_form']: The function name that builds the underlying form that will be updated.
• $form_state['ajax_update']: An array of keys representing the portion of the form that should be updated.
• $form_state['redirect']: If specified, the redirect location will be opened as a dialog, acting as a tool to open a sequence of forms in dialogs.
