Configuration System

[Mierdin]

Need to implement a module that both writes the users configuration to a file (i.e. ~/.pybluedot) on initial setup, and also reads from this file.

Thinking we can implement a command like bdot init and the user will be walked through a wizard for setting up the configuration initially. It will ask for things like the API key, then write those options to a config file.

If the user tries to use any other subcommand, pybluedot will prompt them to run this init command to do the first-time setup. After that, any command should work right away
