DDDCombatRules.getLastHit(UUID) should return an Optional<HitInfo> to avoid NPE's or be changed altogether

Mods like 12M (MmmMmmMmmMmm) fire their own LivingHurtEvent without a LivingAttackEvent. This reveals a fundamental problem:

If a LivingHurtEvent is fired without a LivingAttackEvent, the whole thing crashes.

Either wrap the HitInfo in an Optional, or redo the damage calculation process.

Notes:

• When tentacle spawn via egg it crashes too
• Also when it only fall one block from tainted block to a grass block it crashes
• Spawning it mid air (and let it fall some blocks) cause no crash
