Use paths rather than IDs when submitting job

[Mike Turner]

It would be nice to pass the input data and any excluded folders by path rather than ID when submitting a job.

I'm pretty sure we already do this?
The directory is taken in as a string here:

working_dir = str(raw_input("Base Directory: "))

Then processed in the backend with

def resolve_working_dir(dir_name, request):
    team = get_team_from_request(request)
    location = get_data_location(userprofile=request.user.userprofile,
                                 team=team,
                                 use_active_team=False)
    key = location.s3_obj_key
    folder = Folder.objects.get(obj_key=key + dir_name + '/')
    return folder.pk
