JSHint cleanups
Make redis helper production-ready
Enable express session support via Redis
Add JSHint config files
README updates
Add jitsu/jshint dev dependencies
First steps of passport-based user auth
Move user stuff to a helper class
Reuse Redis connection in BrewManager
Reuse a more Redis connections

Now we're down to requiring only 4 connections rather than 7.

Use bcrypt for passwords

Still a manual process to create users in Redis, but it is possible via
redis-cli and curl to test this whole thing out.
