Limit hsbot responses to major rooms

[ghost]

Rather than removing the scripts that talk back after hearing a specific keyword, we're going to limit them to specific 'big' rooms.

Environment variables will need to be added for each room, and the following scripts will need to handle responding to ONLY those rooms:

• beer.coffee
• bttf.coffee
• deran.coffee
• macs.coffee
• simmer.coffee
• twins.coffee

Updated the bark commands to only respond in Austin, Dallas, Houston, Monterrey, Headspring, and Developers Chat rooms.
