The Phage

there is a major performance fix in this one. phage has a tendency to run amuck underground and while that is part of the design it needed to be throttled or running across new lands and then coming back once the phage has taken hold can basically bring minecraft to stand still. i added some limiters to process only the closest 48 instances and limit the overall processing to a distance of 96 blocks away. this completely fixed the problem in my existing game that i'm testing (where the problem already existed)

bug fixes

fixed/adjusted explosion detection on portals that can be closed that way to work much better.

limited phage growth to areas near the player to fix performance

balance

zoglins, zombies and husks are about half as likely to have the phage when spawned.
