Title: Log refactoring - remove Factory interface & its implementation

Formatter's factory implmentation introduces at ZF1.10
http://framework.zend.com/issues/browse/ZF-9176
This seems for benefit from Zend_Application_Resource_Log.

at latest master (after Intiilapa & ezimuel 's refactor) , Writter & Filter's factory implmentaion is removed.
There is no require implements factory() for Formatter.
And then, Factory Interface is not require at latest master.
