v1.0.3: Custom block models, token textures, admin max overrides, shulker shops and config v2

Stall v1.0.3

Added

• Shulker Box Shops & Large Shulkers:
  • Right-click any shulker box with a Stall token to create a shop container.
  • Players with stall.shulker.large get 54 slots of stock capacity (27 container slots + 27 extra slots).
  • Breaking a shulker shop safely drops all stock on the ground, returns the Stall token, and drops an empty shulker box so items are never hidden in an inventory.
• Custom Block & Furniture Models (CraftEngine, Nexo, Oraxen):
  • Custom decorative block models from CraftEngine, Nexo, or Oraxen can be configured as shops under shops.custom-blocks in config.yml.
  • Configurable stock size per entry from 9 up to 54 slots (clamped to multiples of 9) and customizable inventory display titles.
  • Persistent custom stock storage backed by <world>/stall/custom_stock/<shopId>.json and block tile state PDC.
• Customizable Stall Token Appearance:
  • Configurable item ID via tokens.item in config.yml (e.g. paper, player_head, or custom items).
  • Support for tokens.custom-model-data (integer) across Paper and Fabric.
  • Support for tokens.skull-texture on PLAYER_HEAD, accepting minecraft-heads.com dev 64-bit Base64 strings, textures.minecraft.net URLs, or raw 64-character hex texture hashes with automatic normalization.
• Admin Max Overrides (/stall admin max):
  • Command override system for player shop limits and maximum offers:
    • /stall admin max <limit|offers> <set|add|take> <player> <amount>
    • /stall admin max <limit|offers> reset <player>
  • Persisted in <world>/stall/overrides.json with immediate in-memory caching and precedence over permission tiers.
  • Soft-hook integration with Vault on Paper: automatically cleans up obsolete numbered permission nodes (stall.limit.<n>, stall.offers.<n>) and assigns the newly calculated tier.
  • New permission node stall.offers.<n> (1 to 6) to configure per-player offer limits.
• Configurable Command Aliases & Menu Icons:
  • Custom command aliases configured under commands.aliases in config.yml (e.g. /shop, /market). Command help and usage messages automatically adapt to display the alias used by the player.
  • Full configuration of shop UI item icons in config.yml under menu.icons.* (empty-cost-slot, empty-reward-slot, remove-button, status-available, status-out-of-stock, status-cannot-afford, status-inventory-full, status-shop-full, status-incomplete, status-unavailable, status-new-offer, buy-available, and buy-unavailable).
• Configuration Version 2:
  • Bumped config-version in config.yml and lang.yml to 2.
  • Existing config-version: 1 installations automatically backfill new settings and messages while preserving all custom values and creating a .bak backup.
