- stripped lang prefix for links in regression test - added regression_test for link to file + download option - added delegation to Package->invoke for selected methods "csv-dump", "download", "list". The general question is, whether e.g. a "delete" on a link should delete the link or target, or what the target of an "edit" is, or the target of a download. The first belongs clearly to the link, that last clearly to the target. We should most probably make this configurable and move this decisions to the policy. - derefernece link up to a maximum depth
- overhaul of link support - replaced Package->resolve_request with link-aware item_info_from_url - renamed item_ref_from_id => item_info_from_id - renamed item_ref_from_url => item_info_from_url - added more than 50 tests to regression tests
