Fix error handling in NewPasswordForm
Merge branch '2.0'
Rename \wcf\system\event\listener\IEventListener to IParameterizedEventListener

This is for BC reasons, as PHP does not allow using a class of another
namespace when a class with the same name already exists within the same
namespace. IParameterizedEventListener will be aliased to IEventListener
when \wcf\system\event\IEventListener is removed.
