Config schema

[Canop]

Generate a JSON schema for the configuration files

Fix #372

Usage:

bacon --generate-config-schema > bacon.json

@joshka Self-hosting looks more reliable than hosting at schemastore.org: I can have the update of the schema be part of the release deployment script.

So I'll have this directive at the top of default config files:

#:schema https://dystroy.org/bacon/.bacon.schema.json

As my tools usually accept previous versions of configuration files, I won't add a version suffix unless it really becomes necessary.

Nice! Thanks for pushing that through.
