Support any entity row plugin

If anyone's still interested in this, the base table isn't necessarily the same as the entity type. Taxonomy terms are not the only exception as hook_entity_info() can specify anything as the base table. The correct way to identify the entity type from the base table would be something like this.

foreach (entity_get_info() as $entity_type => $info) {
  if ($info['base_table'] == $view->base_table) {
    $id_key = $info['entity keys']['id'];

    // Collect the needed ids
    $entity_ids = array();
    foreach ($view->result as $row) {
      $entity_ids[] = $row->$id_key;
    }

    // Load all the entities
    $result = entity_load($entity_type, $entity_ids);
    break;
  }
}
