Exact Portals

This mod simply removes the "1:8 conversion" for the Nether, instead making it a 1:1 block coord system.

This causes a lot of weird cases, as sometimes the portal spawns in less-than-ideal spots, otherwise it is awesome for linking up portals exactly.

Portals will search on the exact x + z in the other dimension and start at the portal's y coord. It will scan upwards in that y coord until it hits a portal, otherwise it scans downwards.

If no portal was found it will create a new portal at the exact position and size it was in the original dimension into the other one.

This Creates a perfect link system as no portal will ever link to another x-y coordinate.
