Beta update

config changes:
- added new option in config.yml "allow-removing-old-furnitures_2_3_11" to disable or enable removal of furnitures placed before 2.3.12 update (disable it for performance)
- now you can edit default.json file freely, read more here: https://github.com/PluginBugs/Issues-ItemsAdder/issues/1193#issuecomment-921107747
- added a new special property: "CustomModelData-starting-value" in config.yml. This property allows you to decide a starting CustomModelData for the ItemsAdder custom items. This is useful to avoid conflicts with other plugins.

- removed useless data from mobs (item lore and item display name). This will fix https://github.com/PluginBugs/Issues-ItemsAdder/issues/1170

- fixed various problems with itemframe furnitures rotations
- fixed problem (only if player has high ping) which made furnitures removed as soon as they are placed (already fixed in the past but now increased the delay)
- fixed /iareload and /iazip can be executed during fist load of the plugin generating errors
- fixed plugin can't be reloaded anymore if any uncatched exception is thrown
- automatically remove ".json" after model_path since it's not needed
- optimized resourcepack compression time (-50%)
- optimized model_path validation
- optimized namespacedID calculation (caching)
