DeployerBot sends fires webhooks on command. Although you could really do
anything with a webhook, the intent is to trigger deployments. Therefore the
webhooks are designed mimic GitHub push events.
DeployerBot responds to private messages or channel messages prefixed with the
bot's nick. It will respond to the follow commands:
* deploy <application>
* list webhooks
* add webhook for <application> with url <url> and secret <secret>
* remove webhook for <application>
