feat: replace exploded base_* with public_url

Fixes #1574

BREAKING CHANGE: The `general` section in the config schema has changed: the `general.base_*`, `general.protocol` and `general.force_ssl` configuration fields have been replaced with a single `general.public_url` field. Be sure to use a valid url with the new configuration field.
