NPC Mannequins in Survival

• Mannequin skins will not change when the player changes their skin
• Mannequins drop their respective souls on death

This release supports Paper running Minecraft Java 1.21.9 and 1.21.10.

Developer's note: Likely the last release before v1.0 and this plugin not being in beta anymore. Mannequins created before v0.2.0 may be buggy since this release adds mannequin skins that don't change when a player changes their skin (yay!).

I've tested this plugin very heavily over the past few weeks, but I would like to add one more quality-of-life feature into the main release. Going forward, I would like all mannequins created in 1.. versions to behave somewhat normally going from version to version. I cannot guarantee that this release; hence the v0.2.0 and beta label still and not v1.0.
