Volcanoes (#2) ...

* Initial stab at volcano mapgen

* Make caldera conical, randomized size a bit

* remove grass from underwater soil

* add snow, fix some errors in mountain shape calculations

* improved soil and snow generation, more efficient mapgen

* add some configuration for volcanos, and a find volcanoes command for debugging

* enhance findvolcano, chunk sizes limited to multiples of mapblocks

* more volcano options, also add soil cooking

* update readme and screenshot

* cosmetic tweaks, slight change to default slope range

* fixed the mapgen v7 glitch via a horrible hack :(

* fix the need-to-make-changes test

* use biome-defined material to decorate slopes

* apparently set_lighting and calc_lighting are only supposed to be called on mapgen voxelmanipulators

* add magma chambers at the base of the volcano pipe

* fixes to large-scale grid calculations

* remove a line I added for debugging purposes

* bringing back configurable limits now that the bug's been fixed for six months

* generalizing the heating/cooling ABM

* actually turn the cooling material into the targeted material.

* Revert "actually turn the cooling material into the targeted material."

This reverts commit 508e10acc7c3871cc56fb8347e7931e5595b5f54.

* Fix cooling target node type for real

* very strange, abms don't seem to be updating node groups somehow.

* Workaround for Minetest issue #7864

* using minetest.after proved unreliable, trying different approach

* remove the lava cutoff setting, no longer needed now that veins are fixed

* improve findvolcano command

* using the same solution for v7 mapgen bug as for the lava crash

This is still not 100% reliable, but it's still better than the post-gen patching.

* fix randomization of lava depth

* remove debugging

* extinct volcano lava depth wasn't working right either
