Custom initializers

and some not-so-custom ones.
Redis support for banlists

Also general Redis support

set autoban -> storage to 'redis' in your config.yml and make sure
you have a redis server running. The default port for the server is
6379 and host is 'localhost'. If this does not match your environment,
you can go into initializers/redis-init.rb and change this.

TODO: specify an environment variable that's not 'REDISTOGO_URL' to
place Redis login details
Update gitignore
No more logging of stuff in battle rooms
