Haemorrhage

Extended Bleeding and Health Loss mechanics to affect more entities (when enabled with datapacks)

• spiders applying health loss are no longer hard-coded (you can choose which mobs apply health loss with datapacks)
• it is now possible to make non-player entities get bleeding or health loss after taking damage
• it is now possible to make an entity apply both bleeding and health loss at the same time
• added 5 tags:
  • damage_apply_health_loss (similar to damage_apply_bleed)
  • bleed_resistant_to - mobs from this tag are immune to bleeding and bleedout
  • health_loss_resistant_to - mobs from this tag are immune to health loss
  • can_bleed - mobs from this tag can get bleeding after taking damage
  • mobs_causing_health_loss - mobs from this tag apply health loss
