Merge branch 'hotfix/0.0.0.1' into develop
Extracting `perform` into the HubotGf::Worker class, so that we can keep track of sender/room there instead of fucking around with method arity.
Changed `command=` to `listen`, which accepts a regex and a method
Workers will use a custom method defined by `listen` instead of all conforming to `perform`
Added `reply` and `rebroadcast` methods to workers so no one has to deal with the Messenger object (formerly `gf`)
Multiple commands per worker
Merge branch 'master' into develop
