To do this, I've completely replaced the API between mid-end and front end, so any downstream front end maintainers will have to do some rewriting of their own (sorry). I've done the necessary work in all five of the front ends I keep in-tree here - Windows, GTK, OS X, Javascript/Emscripten, and Java/NestedVM - and I've done it in various different styles (as each front end found most convenient), so that should provide a variety of sample code to show downstreams how, if they should need it. I've left in the old puzzle back-end API function to return a flat list of presets, so for the moment, all the puzzle backends are unchanged apart from an extra null pointer appearing in their top-level game structure. In a future commit I'll actually use the new feature in a puzzle; perhaps in the further future it might make sense to migrate all the puzzles to the new API and stop providing back ends with two alternative ways of doing things, but this seemed like enough upheaval for one day.
