Jhbate/csv via cl

@jebeck here is the cli for uploading carelink data if you could have a look.
I'm not happy about this. A couple of weeks ago, @nicolashery removed the configuration information from the build -- and now it's going to be back in this form.

I really believe that this information should only be in one place -- so if we're going to not have it in the source, I think that this module should also be dependent on a config shell script.
