RC Spent/Recoverable Ammo Tracker

Made for the DnD5e system. In 5e, after a combat, you can choose to spend 1 minute to recover half of expended ammo, rounding down. My players hated tracking their spent ammo each combat and trying to remember to recover it, so I made this module.

How it works:

• When you Create Encounter, it records the current quantity of any item with consumableType == 'ammo' (ie. arrows, crossbow bolts, etc.)
• When you hit End Combat, it counts how much of each ammo type was spent
• For spent ammo, it whispers to the actor how much was spent and how much can be recovered
• The message includes a Recover Ammo button, which both updates inventory and posts a public message indicating the recovered ammo
• Tracking works fine across sessions/different devices, as all intermediate data is stored in flacts on the actors

Assumptions/Known limitations:

• Currently, this works by finding all actors linked with game users. If a player owns multiple actors, this may misbehave
  • The GameAmmoTracker class accepts an optional list of actors in the constructor. If you want to contribute controls/settings to improve this, be my guest.
• Behavior is undefined when ammo is fully depleted
  • The message will post, but the recover button will not work since there will be no item in the character sheet to update the quantity on
  • This is a rare enough edge case that I couldn't be bothered to deal with it
• Behavior is undefined if you create and end multiple combats at a time; I never do this.
  • I suppose I could listen on beginCombat (or maybe it's startCombat?) instead of createCombat. If you care, make a PR :)
