Implement hook_action_info and others to integrate with VBO

Well, I'm attaching a small module that adds "approve" and "decline" actions for Views Bulk Operations for 6.x branch of Userpoints. To make it work you also need to describe txn_id column to views: add

  $data['userpoints_txn']['txn_id'] = array(
    'title' => t('Transaction ID'),
    'help' => t('Transaction ID'), // The help that appears on the UI,
    'field' => array(
      'handler' => 'views_handler_field_numeric',
      'click sortable' => TRUE,
    ),
    'sort' => array(
      'handler' => 'views_handler_sort',
    ),
  );

to userpoints.views.inc

@saday: I haven't quite got what you're talking about. Could you please post screenshot of VBO settings from views admin page and screenshot of your actual view? Thanks.

#5: I cannot reproduce your issue. I tried playing around with the settings on my installation, moving and even removing transaction id from fields, but VBO selection always stays fine. So I can give you just suggestions of general character like: clear cache; try changing operations selection from drop-down list to buttons; try checking other operations to make sure they work etc. If this doesn't help, I can have a look at your installation. If you'd like this, contact me via pmb.
