loudbot is back

I published a package called loudbot - https://github.com/oren/LOUDBOT
I added it to package.json and changed the loud.coffee to use the loudbot package.

notice that you need to add another export for loudbot - 
export LOUD_CONFIG=/path/to/config.js/where/you/store/twitter/keys

there is one issue with twitter, they are limiting the number of requests we can query so if we hit loudbot too often we'll have to wait a bit. we can add some simple caching if it will become an issue.
