Deploy recipes, and config templates.

1. Deploy recipes for sc-server applicaiton
This makes use of Chef's deploy resource which is very similar to Capistrano.

2. Cookbook to deploy sc-emitter application
This is very similar to sc-server. Probably we need to DRY these up a bit

3. Change the deploy checkout from master to deploy
Otherwise it will conflict with the actual master branch.

4. Change the git repo for sc-emitters
The old one was failing!

5. Template for sc-server config
This config.js is now loaded from this template. We can change the attribute values according to different roles.

6. Remove port from the init script for emitters app
Emitters app doens't need a port to run. It's just a node process.
