Allow to disable fall-back CAPTCHA for text analysis

This is a feature that is currently in the pipeline, see #1020072-8: Rethink/simplify UI to protect/configure a form for details.

We'll be moving the implementation part for the new unsure configuration parameter into this issue, so thanks for creating it :)

Attached patch implements additional support for the "unsure" parameter of the Mollom API:

+1

Re-rolled against 7.x-2.x.

Last remaining todo for this is to verify that we're sending the unsure parameter, the proper value for it, and only when it's applicable (checking for spam).

Is there a plan to make it available for D6?

The patch from #5 works perfectly for Drupal 6. You will only need the update function fixed.

/**
 * Add {mollom_form}.unsure.
 */
function mollom_update_6122() {
  $ret = array();
  if (!db_column_exists('mollom_form', 'unsure')) {
    db_add_field($ret, 'mollom_form', 'unsure', array(
      'description' => 'Whether to allow (1) or disallow (0) "unsure" text analysis results.',
      'type' => 'int',
      'size' => 'tiny',
      'not null' => TRUE,
      'default' => 1,
    ));
  }
  return $ret;
}

Sorry, this is now a duplicate of #1834860: Allow to accept "unsure" posts as ham without CAPTCHA or further validation (binary mode).
