Implement work-in-progress api, parse config

The command just spits out what it would do/send to the rails server
right now. It will search for an upload url in this order:
    - command line option
    - environment variable
    - ./.yarddog.conf
    - ~/.yarddog.conf
    - if none of the above work, it uses http://localhost:3000
