Add hook_honeypot_reject so other modules can react to rejected form submissions

I recently replaced my homebrew solution to this problem with the honeypot module but this feature was one thing that the module lacked in comparison so I have a patch against 6.x-1.14 attached.

I added the $type variable to the hook_ call because I want to auto-ban anything that submits the honeypot field, but not ban someone that trips the time limit because there is a much bigger chance that they could be human as the time limit applies across all forms, not individual ones. eg. 5 seconds is great on the registration form that needs time to fill out but not so good on the reset password field where it can be beaten manually.

This is my module code that uses the troll module for anyone interested:

function mymodule_honeypot_reject($type, $form_id, $uid) {

  // Troll ban anything that fails the honeypot protection
  if ($type == 'honeypot') {
    $expires = getdate(time() + 604800); // Expire IP block after 7 days
    
    troll_insert_ip(array(
        'ip_address' => ip_address(),
        'domain_name' => 'Caught in a honeypot',
        'expires' => 1,
        'day' => $expires['mday'],
        'month' => $expires['mon'],
        'year' => $expires['year'],
            )
    );

    exit;
  }
}
