Renaming for Kohana.
Simplified the module upon many considerations.
Removed api_url, it is determined in __constructor instead.
Tests are working (but not passing yet!).
Added missing NotifyValidate class.
factory() returns a Request object instead.
Redirection calls are static.

Fixed DoReauthorization.
PayPal::factory() returns a Request object.
PayPal is more static and used as a helper on Response objects.
Worked on tests.
