Title: Inherit from pdo

This makes OLB_PDO inherit from PDO. Which is a little weird because we never allow the regular PDO constructor to be called, but it does buy us a few big things:

* It lets us inherit all of its constants.
* It allows our wrapper to be used anywhere a method has a class constraint on PDO.
