Less Simple Void World

LSVM is a fork of simple void world.

Additions

• Fuzzy Portals - Portals now search an 8 block radius (configurable) for the nearest portal
• Y-64 Relaxation - Portals can now be configured to not forcibly spawn at Y=64. Defaults to y-64 to maintain backwards compatibility.
• Backwards Compatibility - If the portal cannot find the original portal because it's not within the radius, it will search for it in a vertical square (from 0-255 if in overworld, around 64 in the radius if in the void).
