- User-related database methods will now throw User\Exception upon errors
- Internal userAdd method can now generate random passwords
- Pursuant to above, dependency on password genrator has been added, and password-related methods now return strings instead of booleans
- User class methods now all explicitly follow different branches for internal/external/missing implementations
- various User class methods now perform auto-provisioning of the internal database when external implementations report success on users not in the database
- Tests have been adjusted to account for the above changes
- Lots is probably still broken
