Clean up WebNavigationObserver by taking out password specific callbacks, and make PasswordManager just dispatch the IPC message directly to achieve this.  I've also combined WebNavigationObserver with IPC message filtering (I hadn't seen the former when I added it).  This allows a little more cleanup in AutoFillManager.
