user_admin_access_form ignores the default value for Access Type

When creating access rules in the user.module, the edit screen (admin/access/rules/edit/) does not reflect the actual setting stored in the database and will always be 0 (Deny). Editing an existing access rule will therefore flip from Allow to Deny when one doesn't pay attention. This can potentially lock the drupal system.

Here is a code snippet from the user.module:user_admin_access_form function with the suggested change. I simply passed the $edit['status'] value to the #default_value which fixes the mis-beavior

function _user_admin_access_form($edit) {
  $form['status'] = array(
    '#type' => 'radios',
    '#title' => t('Access type'),
    '#default_value' => $edit['status'],
    '#options' => array('1' => t('Allow'), '0' => t('Deny')),
  );
