Avengers Token SMP Mod

• Added four collectible tokens (Captain America, Thor, Hulk, Iron Man) that grant themed abilities when used.
• Use /avengertoken list to see available tokens and /avengertoken give <player> <token|all> [amount] (permission level 2) to distribute them.
• Tokens are single-use items (not consumed) with cooldowns: they trigger a power and then wait before reactivation.

Abilities

• Captain America Token: Line-of-sight shield strike, with short Speed II, Strength II, and Resistance I buffs.
• Thor Token: Calls lightning at what you target, launches you upward, grants temporary flight, Slow Falling, and Resistance.
• Hulk Token: Ground smash damages and knocks back nearby foes, then grants Strength III, Resistance II, Jump Boost III, and brief Regeneration.
• Iron Man Token: Repulsor beam damages/knocks back what you aim at, spawns smoke on blocks, dashes you forward, grants hover flight plus Fire Resistance and Slow Falling.

Notes and limitations

• Tokens are intended for server ops to hand out; there is no natural drop or crafting recipe.
• Flight from Thor/Iron Man is temporary and removed automatically unless the player is in creative/spectator.
• Effects run server-side; clients only need the included resource assets for item visuals.
