Legacy old PvP

First release.

• Spam clicking, no sweep attack (damage, particle and sound), 1.8 damage with nerfed axes, 1.8 knockback, armour, regeneration and golden apples.
• Sword blocking on every version: the sword itself blocks on 1.21.5+ (Paper, Folia, Spigot), a resource pack disguise on older servers, and the sword itself again for 1.21.2+ clients through ViaVersion.
• Minigame extras (click bow, click reload crossbow, crossbow insta shot), all off by default.
• Tested with bots on ten server versions plus a ViaVersion setup and a 150 ms latency run, and played by hand on six servers.
