[Custom Npcs 2] Custom Death Message System

[Pychnight]

Converted from https://github.com/Pychnight/Custom-Npcs-2/issues/23

What is a death message?

• death messages are messages sent to the client upon being killed by a npc or projectile
• https://terraria.gamepedia.com/Death

What's this function do?

• Over rides the default death messages sent by the monster or projectile with the custom one.
• support non-custom projectiles that monsters shoot..

How it currently works

• HurtPlayer(TSPlayer player, int damage, bool critical, string deathReason)
• KillPlayer(TSPlayer player, string deathReason)

as you see we kill the player and send the death message.

Why this is bad?

• players will unexpectedly randomly die to send a custom death message when they have full hp.
• can't really use this in any kind of logical script as custom npcs you don't have access to players values most of the time..
