Prepare message from string or object

[timkinnane]

Closes #146.

sendMessageByRoomId now accepts the default string message but will also take an message object, which can contain attachments. If message object is sent, it will readdress that message to the given room ID.

Example of taking an attachment from one message and sending it to someone else with hubot, inside listener:

if msg.envelope.message.hasOwnProperty('attachment')
  newMsg = {
    msg: "See attached:",
    attachments: [msg.envelope.message.attachment]
  }
  robot.adapter.chatdriver.sendMessageByRoomId newMsg, roomID
else
  # wasn't sent attachment

You know this kind of makes my customMessage method useless 😁 But good addition. Thanks 👍

Oh @geekgonecrazy, I didn't even see that 😛
I was following from work by @ngenerio that allowed the receiver to accept attachments on the message object, extending the send method to allow passing the original message directly through. Thanks for the merge!

@timkinnane sure thing. I'm looking to cut a release soon. Just have to verify #154 fixes things for users with version 0.37.0 of Rocket.Chat. My tests indicate yes. Just want to ensure its not just me.
