Site move

The PG-DE site is now hosted at https://www.projekt-gutenberg.org/ though the old mirror still exists, for now. Author IDs and URLs have changed from (example) this to this. I propose we change this property accordingly; the contents is the same but who knows how long the old site exists. I have ported the existing matches in Mix'n'match into a new catalog which could be synced back to WD after we remove all existing Projekt Gutenberg-DE author ID (P7753) statements. The new catalog is slightly smaller but that may be due to cleanup (less duplicates AFAICT). --Magnus Manske (talk) 09:02, 7 January 2020 (UTC)

@Magnus Manske: I agree: if there are no objections, tomorrow I can remove all old statements. --Epìdosis 09:12, 7 January 2020 (UTC)

Old statements removed and regex updated; now @Magnus Manske: could you remove P7753 from old catalog, which should be deactivated, and add P7753 to new catalog? Thank you very much, --Epìdosis 18:26, 8 January 2020 (UTC)

Thanks, changed the catalogs, syncing now. --Magnus Manske (talk) 15:00, 9 January 2020 (UTC)
