Updated __init__.py files for new structure.
Moved mx-requirements.pip to /pkg/ dir.
Fixed module structure, again, due to directory layout change.
Fixed a missing comma in the logger in util/log.py.
Added main file for starting the remailer, still need to finish
check_recipient, added logging functionality, and config is halfway done, but it will need to use JSON rather than Yaml.
Need to switch the config to JSON following leap_client.
