allow jumping to unexplored areas (actually tested)

[The4codeblocks]

also adds better error handling by displaying every error/warning where applicable

lgtm so far, but i would rather add a setting to enable jumping into the unexplored map-parts, do you want to do that or should i do it in a follow-up PR?

should i do it in a follow-up PR?

I think so

@The4codeblocks in case you want it fast then better just add that configuration here with this PR and keep jumping to unexplored areas disabled by default to keep both behavior and max safety.
In case you want it when other people are ready then just wait a moment and it'll get sorted out eventually.

Besides config naming comments settings could be moved here:

jumpdrive/init.lua

Lines 2 to 20 in bb66479

	jumpdrive = {
	config = {
	-- allowed radius
	max_radius = tonumber(minetest.settings:get("jumpdrive.max_radius")) or 15,
	max_area_radius = tonumber(minetest.settings:get("jumpdrive.max_area_radius")) or 25,
	-- max volume in nodes ( ((radius*2) + 1) ^ 3 )
	max_area_volume = tonumber(minetest.settings:get("jumpdrive.max_area_volume")) or 29791,
	-- base storage value
	powerstorage = tonumber(minetest.settings:get("jumpdrive.powerstorage")) or 1000000,
	-- base technic power requirement
	powerrequirement = tonumber(minetest.settings:get("jumpdrive.power_requirement")) or 2500,
	},
	-- blacklisted nodes
	blacklist = {}
	}

But don't think that's super important, but if you happen to have a little bit extra time to move stuff.

Should this be tested on actual server (thinking about pandorabox test server)? I bet that could be arranged too and some players might be willing to test it there too.

That said seems simple enough to me to possibly just get merged without extensive testing... and now that there's disabled by default config IMO rate limiters can wait for another PR.

I agree

Looks good to me but didn't actually test it.
Should be safe too as it now requires explicit configuration to enable jd mapgen.

hm?
