Title: Update item-pipeline.rst

Modifying DOCs to mention the undocumented boiler pipe required to make item pipeline methods work correctly (see: http://stackoverflow.com/questions/4113275/scrapy-pipeline-spider-opened-and-spider-closed-not-being-called). Perhaps a better long term solution could be creating a generic pipeline base class?
