Implement custom attack speed as config option, useful because the npc
stats data we have from wiki isn't 100% correct, or isn't even there.
Add minimum attackrange of 1.
Enable timer when the player is interacting with their target.
Add default attack speed of 4 when wiki doesn't provide the data.
Fix splash flinching while using a better method to implement it, using
the function "onSpotAnimationChanged".
Remove deprecated variable "lastspotanimation".
Remove unused variable "lastTickUpdate".
