Main compatibilty - http api workaround when server forgotten access

* http api access must be using configuration, so check first in init.lua
* Merge branch 'main-compatibilty' of https://github.com/mckaygerhard/essentials into main
* provide backaguard falback on older servers, biome data functions missing
* will work with 0.4 servers like just test and famous subnasa
* make it work with older versions of minetest
