Changed approach to reset.
Now allowNether must be false in the server props.
This plugin now creates world_nether and is such, able to unload it
Still needs an NMS call to force region files to close though.
Started added portal system

Currently can create a link portals, but not a full link.
Doesnt yet create the portal blocks (still looking into why)
Portal placement needs work

Portals need to be saved
