Title: Zend\Log refactoring

Refactoring of Zend\Log according with RFC:
http://framework.zend.com/wiki/display/ZFDEV2/RFC+-+Log+refactoring

Moreover I did the following changes compared with the previous version of Zend\Log:
- removed custom priorities in Zend\Log\Logger;
- removed setEventItem();
- removed factory (using plugin broker for writers);
- removed Zend_Layout in the Zend\Log\Writer\Mail;
- removed Zend\Log\Writer\Firebug (because we need to refactor Zend\Wildfire before)
