This is the glue code between the map generator and the luanti code

You register items and monsters with the dungeon generator mod, mg_arch.
As part of the linking, there will code that will link it to the luanti node or entity and 
what to do when spawning the item in the luanti world

mg_arch is not suppose to have any dependencies, this is spun out as a seperate mod so that 
it can depend on other mods as part of the item initializtion process.  For items, this is for 
things that need enchanted and the enchant code is specific for that mod.

mg_game mod takes mg_arch and this mod to generate the dungeon in the minetest world
