Fabric

More automation, whee!

To have access to some fun new commands, you'll need to update your requirements.
```
pip install -U -r requirements.txt
```

So far, I've tested the commands to make it easier for people to work with locales/translations.
```
# Generate the localization files
fab prepare_locale:de
# After you edit stuff in locale/de/LC_MESSAGES/
fab compile_locale:de
```

Will soon be testing other components.
