FEATURE: Added specific config option for swarm_channel

This enables a split between the channel used for CC by humans
and the chatter by the bots
FEATURE: Random wait and vote-collition

The bot now waits for 0-60/10 seconds and checks so it's own
vote isn't already in the vote-dict
FEATURE: Move settings to db

Settings are now in a db that are populated with default values
if something is missing.
