Implement a super basic deploy. If anything isn't properly in place it will fail pretty hard for now.

QA
-----------

1. Make sure you have a .fog file in your home directory
2. create a .opstwerk file with an opsworks stack_id and app_id
3. run the deploy command
```
ruby -Ilib ./bin/opstwerk deploy opsworks_staging
```

once the gem is bundled we won't need the special ruby lib include dance.
