Freezing Water

• Freezing Water can be only found in very cold biome types, only in following biomes: Icy Spikes water bodies, Snowy Mountains biome, Frozen Ocean biome and Deep Frozen Ocean biome.

Freezing Water mechanics:
With a 5second delay (if submerged for 5 seconds) player will only get "Freezing Effect" on screen trough-out time. After 5 seconds, it will start damaging the player by 1HP(0.5 Hearths) per 3 seconds. 
Freezing water can also give "smmal blue snowy" paticles just to be seen more easily.

Cold-water behavior could be controlled through a biome/fluid tag such as Freezing_Water.
("Freezing_Water:true" or "Freezing_Water:false", only naturaly spawning.)

Wearing a Leather Tunic completely prevents the freezing damage, as leather provides insulation and helps keep the player's vital organs warm.
