Add Support For Multiple Rooms

• added simplified setup through npm link (docs needed)
• added support for multiple rooms

Can I get some 👀 on these changes?

Looks good. Some reason doesn't work through docker.

Couple of little things:
ROCKETCHAT_ROOM probably should just have GENERAL in it. Since that other rooms id will be different on other servers.
ROCKETCHAT_URL probably should be localhost by default

Just tried it here, in my 'lab environment', on docker as well.

WORKED like a charm. @geekgonecrazy - please merge it down once you confirmed. Tested for general + one other room.

TWO gotchas, nothing to do with the code, I encountered:

• forgot to pull down new docker image - docker pull singli/hubot-rocketchat
• forgot to do npm install after git clone of lee's branch

After that, I just edited the ROCKETCHAT_URL, the ROCKETCHAT_ROOM list, user and password; I also tested @geekgonecrazy 's BOT_NAME change by using -e "BOT_NAME=yeahbaby" and it worked fine.

Had to purge node_modules and do npm install again. Now works.

Maybe we can include some of this in the image in the future

I have some notes I need to add to the Hubot documentation around how to build without requiring a Hubot dependency. That will make it easier for deployments too.

@leefaus sounds good. No fun writing documentation, but sure is helpful 👍
