Add Ignore User support

Relevant code:

  if ($type == 'node' && $user->uid != $object->uid && $object->uid != 0 && user_access('ignore users')) {
177	    if (!isset($ignored[$object->uid])) {
178	      $ignored[$object->uid] = db_result(db_query('SELECT COUNT(*) FROM {ignore_user} WHERE uid = %d AND iuid = %d', $user->uid, $object->uid));
179	    }
180	    if ($ignored[$object->uid] == 0) {
181	      $links['ignore_user'] = array(
182	        'title' => t('Ignore user'),
183	        'href' => 'ignore_user/add/'. $object->uid,
184	        'query' => 'destination='. $_GET['q'],
185	        'attributes' => array(
186	          'class' => 'ignore-user',
187	          'title' => t('Add user to your ignore list'),
188	        ),
189	      );
190	    }
191	  }
192	  else if ($type == 'comment' && $user->uid != $object->uid && $object->uid != 0 && user_access('ignore users')) {
193	    if (!isset($ignored[$object->uid])) {
194	      $ignored[$object->uid] = db_result(db_query('SELECT COUNT(*) FROM {ignore_user} WHERE uid = %d AND iuid = %d', $user->uid, $object->uid));
195	    }
196	    if ($ignored[$object->uid] == 0) {
197	      $links['ignore_user'] = array(
198	        'title' => t('Ignore user'),
199	        'href' => 'ignore_user/add'. $object->uid,
200	        'query' => 'destination='. $_GET['q'],
201	        'attributes' => array(
202	          'class' => 'ignore-user',
203	          'title' => t('Add user to your ignore list'),
204	        ),
205	      );
