Tracking modern support lacking features

[Pablete1234]

Most if not all PGM features have been reimplemented in the newer features, with some exceptions:

• CanPlaceOn/CanBreak: Fixed in Update dependencies to 1.21.1 #1394
  • Removed in 1.20.6 spigot/paper due to changes in vanilla.
  • Hoping to add them back when they re-add them in 1.21 or something.
• Knockback reduction kit
  • This relied on a sportpaper only patch to set a multiplier to the kb taken
  • Can maybe be replaced with a knockback resistance attribute, since i belive that's what it does in newer versions (in older versions it was a % chance of receiving 0 kb, instead of a multiplier on kb taken)
  • If not, paper now launches an event when KB is taken and we can modify it there
• Extra data in ping packet
  • This was also a sportpaper exclusive, we can't freely modify the ping packet to add extra data in paper
• Observers seeing invisible players
  • sportpaper exclusive. Obs will not be able to see invisible players.
  • Maybe can get this back by modifying packets in protocol lib.
• Hide all potion particles for players
  • sportpaper feature that PGM enabled by default on all kits who didn't explicitly disable it, only ghost squadron really disabled it.
  • Modified it so instead it will make kit potion particles ambient, no need to fully hide them.
  • Can probably get this fully back by modifying packets in protocol lib, but is a good candidate for an actual behavior change in legacy too.
• Can't track entities spawned by dispensers (BlockDispenseEntityEvent)
  • If the spawned entity (arrow, spawn egg, tnt, etc) deals damage to someone, it doesn't count as yours for having placed the dispenser
  • This is likely very hard to work around, if at all possible
• Can't track who caused an explosion (eg: tnt or creeper) (ExplosionPrimeByEntityEvent)
  • When you shoot a tnt with flame, or light a creeper with flint & steep, it can't count that explosion as yours
  • When a TNT you lit, makes another tnt go off, it can't count it as yours either
  • This is likely very hard to work around, if at all possible
• EntityExtinguishEvent is missing, this should only be an internal technical issue as certain state doesn't get cleaned up, but shouldn't see feature differences.

I hope these are relevant to this issue:

• The icons in the settings menu are all ink sacs, probably because they use damage values but are now items.
• potion duration="oo" should probably be made into actual infinite duration. [ref]
• Maps previously on level 0 are no longer at the void, consider adding a setting similar to maxbuildheight that determines the lowest possible build limit.
• Auto-learn all recipes (make sure to disable all advancements in spigot.yml.
