Add support for limiting node creation in ALL OGs

i'm going to be lazy and not roll a proper patch for two lines of code. sorry. my changes are for the case where each OG should only have one of a certain kind of content type. for example, the og page contains only the og description, and each og has a 'club officers' page associated with it. you don't want more than one of those per group.

the first change is this:

if (module_exists('og')) {
    // if settings['og'] is equal to none this is a simple limit
    if ($settings['og'] != 'none') {
      if (is_array($node->og_groups)) {
        // Loop through each of the og settings to find enabled
        foreach ($node->og_groups as $node_gid) {
          // Loop through each of the groups for the node to see if they match
          if ($settings['og'] == $node_gid || $settings['og'] == 'all') {//<-----------------------------------changed this line
            // The node matches the group with the limit
            // Find all nodes that have been created for that group
            $q = "SELECT * FROM {node} INNER JOIN {og_ancestry} ON node.nid=og_ancestry.nid WHERE og_ancestry.group_nid = %d";
            $result = db_query($q, $node_gid);
            $num = db_affected_rows();
            if ($num >= $settings['limit']) {// We have the data, now we check the limit
              return TRUE;
            }
            // Did not match but we still need to loop through the rest; not returning false
          }
        }
      }
      return FALSE;
    }
  }

the second change is this:

if (module_exists('og')) {
    $q = "SELECT nid,og_description FROM {og}";
    $result = db_query($q);
    while ($data = db_fetch_array($result)) {
      $node = node_load($data['nid']);
      $groups[$node->nid] = $node->title;
    }
    $groups['none'] = t('None');
    $groups['all'] = t('All');//<----------------------------------------------added this line
    $form['settings']['og'] = array(
      '#type' => 'radios',
      '#title' => t('Limit By Organic Group'),
      '#default_value' => $settings['og'],
      '#description' => t('This limits the amount of group posts'),
      '#options' => $groups,
    );
  }
