Move AppFog specifics to some different files

app.js is an AppFog shim that acomplishes the following:
- Require CoffeeScript
- Sanitize comand line arguments removing extra params
- Start "status" server

status.coffee is currently just a simple HTTP server to monitor
the current command line options the repost program got.

Also, app.js will simulate the command line arguments by using
env variables to avoid sensitive information been sent to Git.
