Update FacebookHelper.php

When I tried to use a custom facebook connect button the permissions that I asked for did not work at all. 

I modified the facebook helper and now everything is ok and working as it should.

Please update the files. Thank you!
Updates for compatibility with v2.4

The AuthComponent::password is being deprecated and calling it causes errors if you use 'blowfish' as Security::$hashType. If it needs to be a specific hash then it should be passed in as a second parameter
