Huge changes - see inside

Main new feature: Multiple bots

Each bot is defined in the config file:

bots:
  - <CONFIG FOR A BOT>
  - <CONFIG FOR A BOT>

(see config-example.yml)
Remove old logs folder
Update config-example.yaml
Removed mafia directory

Move the password for autoban into the config.

This involved making another trigger field: 'init'

use it like this:

t.init {
  what to do when trigger is initialized
}

Right now it has use because in the main body of the Trigger.new block, t[:ch] is not
initialized. In the init block, it's guaranteed that t[:ch] will be set.

Add config info to README
Remove useles file
Clean out some more useless files
