If you are upgrading from a previous release, you need to either delete all existing database tables or create a new
DB, followed by running `fangfrisch initdb`.
- Clean up previously downloaded files when their local path changes.
This can happen when `filename_xyz` entries are added or modified.

- When a provider section is disabled, clean up associated virus signature files.
This feature can optionally be disabled using the new `cleanup` configuration parameter.
Suggested by amishmm.
- Running `fangfrisch --force initdb` will attempt to drop existing tables.
- Introduce the *dumpmappings* action.
This allows passing URL-to-filepath mappings recorded in the database to utilities like `awk` without accessing the
DB directly.
