Changing Drupal username triggers new user in QW

[emasters]

We need to check something beyond just username when coming to QW from Drupal in order to account for changes in username. For example we could chacked the stored user object in QW to make sure that the Drupal uid matches the current login attempt and then update username, email, and even password, as necessary.
The new check should be in drupal_user.php around
