Discovered many problems with the abstractions along the way
and did small fixes to get to the end of the auth module.
- Use more constants for random strings
- Create forcing functions to deal with the upgrades to different
interfaces
- Replace the old logging mechanisms with a leveled one. This is
important as authboss needs to start saying a lot more about what's
happening in the Info log, which will end up like Debug but that's
okay.
- Replace the error handling mechanisms with something different. This
allows people to define their own error handlers.
