Feature Request: cli option for generating default configs

[jessebot]

Describe the feature you'd like, and why

We should have a function and cli option for generating basic config files. It just needs to take the default configs and place them in the user's $XDG_CONFIG dir. This way the user has the default configs and can play with them, as well as can overwrite their existing config with fresh known-working configs.

Perhaps CLI option/switch like -c and --config. I don't actually want to take a config file at this time, because then the accepted config gets really complicated and I will need refactor the env_config.py file (which is kinda overdue anyway).
