[Feature Request] mob ability configuration

[Yourname942]

As a client I want to have the ability to configure each mob's abilities, so that I can disable/edit ones that we do not like, so that we don't have to completely disable certain mobs.

Examples:

• to disable the 1 hit kill chance from cockatrice, or at least set it to 0% chance
• to blacklist certain potion effects for the beholder's beam
• to prevent music discs from dropping on killing destrachan
• to prevent fire spreading from hellhounds
• to disable the webs from caveFisher
• to have the cafeFisher's webs dissapear after a certain amount of ticks (configurable amount of time)
• to configure how much damage the manticore's spines do

thank you.
