* Zombie attacks don't infect if they are blocked by shield;
* Cancelled any work on Cyberzombie and removed all traces of it from code :(
* Added option to replace skeletons in overworld with zombies
(CAUTION: VERY BUGGY! MAY BREAK WORLD! ENABLE AT YOUR OWN RISK! ESPECIALLY ON DEDICATED SERVERS!);
* Random zombies never turn into chestheads anymore;
* Random zombies now turn into zombie villagers sometimes;
* Random zombies turn into frozen lumberjacks only in snowy biomes;
* All modded zombies now drop something useful instead of rotten flesh by default;
* Chestheads by default drop rotten flesh and oak planks;
* Reduced buffs on miners & warriors by 1;
* Tough zombie buffs now are removed and re-applied on world load, to prevent effect accumulation;
* Zombie senses now are somewhat pre-configured by default;
* While zombies attack endermen in feral mode, they, in theory, should never win the fight;
