forked from minetest-mods/nether
Update copyrights & require Minetest v0.4.16 or greater
Also adds nether.register_wormhole_node(), moving the wormhole node template into portal_api.lua, and allowing wormhole nodes with custom post_effect_color to be more easily created.

takes on when you are standing inside a portal. `post_effect_color` is the

only key/value that is needed in the nodedef_overrides table to achieve that,

new wormhole node.
