bcrypt in addition to devise

[alec-c4]

Hey!
I'm writing just because of issue #50, and I'd like to propose you an idea. What about to add ability to use this gem with bcrypt based authentication?

Hey @alec-c4, it should already be possible (unofficially) to call AuthTrail.track directly in the controller where you're doing the authentication - #22 (for instance, SessionsController with Rails 8 authentication). Will consider making this part of the official API / docs.
