Add new "config" command when starting Butler SOS, creating a default config file

[mountaindude]

Something like butler-sos.exe config would create a config file with correct structure for the version of Butler SOS being used.
This will make it easier to get started with Butler SOS.

• All features that can be turned on/off should be turned off.
• Use butler-sos-config.yaml as output name. Warn if the file already exists.
