api4webtrees 1.18.0 – API level 30, the interface is complete

API level 30: the interface is complete. With this release every route needed for everyday genealogy work is there:
individuals, families, events, names, sources and citations, media, places and location records, godparents, merging with
undo, and now research tasks, ordering, change history and favourites. From here on releases will be rare. Changes
and fixes are collected and published together; pull requests are merged without an immediate release, so clients built
on this API are not served a new version every few days. Everything is additive; older clients keep working.

• Bookmarks → webtrees favourites. GET/POST Bookmarks now use webtrees' own favorite table, so the bookmarks appear
  in the browser under “My page › My favourites” and survive any client. data are the user's, treeFavorites the
  tree's (managers set them with forTree: true), each person with a note. Bookmarks from the old user setting are
  taken over once, automatically.
• Research tasks. GET Tasks lists webtrees' _TODO facts of the tree (text, date, user, note; ?open=1 only the
  ones due); POST Task adds or changes one (date defaults to today, user to the signed-in one); deleting with
  DeleteFact means done. Individual and Family answer with tasks. Nothing proprietary: _TODO is what the
  webtrees module “Research tasks” writes and shows.
• Ordering. POST Reorder sorts children, partnerships, names or media – like the “Re-order” pages in webtrees,
  only the order of the GEDCOM lines changes.
• Change history. GET Changes lists who created, changed or deleted which record and when (webtrees' change table,
  pending changes included), ?xref= for one record; Individual and Family answer with lastChange (CHAN).
• Tests: StufeDreissig (favourites with migration, tasks, ordering, history); the documentation is generated again.
