Typo: 'Deleted answer puzzle' -> 'Deleted answer for puzzle'
Argsify getByName

The reason for converting these functions to taking (args) is that
hubot calls them over the ddp interface, and a ddp call can only pass
a single "params" argument:

DDPClient.prototype.call = function(name, params, callback) {
  ..
  self._send({msg: 'method', id: id, method: name, params: params});
}
