[development] form with confirmation (sometimes)

[Pierre Rineau]

The $form_state['rebuild'] forces the form API to rebuild the same form,
using the same processing function, but instead of giving a empty
$form_state, it gives a full filled array with values you set into.

Somehow, in validate then submit, you do a $form_state['delete'] =
array(<your nid's here>), then, in you processing form function, you can
catch the $form_state if not empty (and filled with your 'delete'
attribute), then you can use a if statement to build a different form
(in your case, a simple config_form(), with an altered '#submit' which
will be the real delete operation submit callback).

Hope it helps.
