blacklist: implement `get-url` function from `reference` and `id` fields

The blacklist allows referring to a number of trusted bug trackers to
complement the information given in the reason field. However,
maintainable shorthand identifiers are used instead of full
URLs. Printing the latter based on the former is the job of this new
functionality.

This also introduces corresponding test cases and l10n strings
(together with translations for the `es` locale).
