Title: Fixing PingbackableBehaviour parse error

See issue #55

Seems like the PingBackable behaviour wasn't tested at least through lint:

php -l PingbackableBehavior.php
PHP Fatal error: Can't use function return value in write context in PingbackableBehavior.php on line 63
Errors parsing PingbackableBehavior.php

This was using caused by using the return of is_array() in empty().
