function resource_conflict_field_delete_instance in Resource Conflict 7.3

Implements hook_field_delete_instance().

If this field was assigned as an RC date field, we want to delete it's data from our registry and possibly warn the user that RC was disabled for this content type.

    variable_del('rc_date_field_' . $instance['bundle']);

    // Msg user if the content type was enabled for RC.
    $content_type_enabled = variable_get('rc_type_' . $instance['bundle'], FALSE);
    if ($content_type_enabled == 1) {
      $msg = t('Resource Conflict has been disabled for the %type content type as the date field has been deleted.', array(
        '%type' => $instance['bundle'],
