- Replaces the old hardcoded drawing methods with a new json-based system with support for multiple inbuilt and resource pack-defined skins.
- Adds a config option for choosing the spell HUD skin, along with a custom config GUI screen allowing the user to select from a list of available skins with a preview of the currently selected skin.
- Replaces the HUD texture file with a spell_hud subfolder, containing all the necessary textures and json files for the 12 inbuilt skins.
- Adds a subtle sound effect and scroling animation when switching spells
- Reorganises the control event code into a single handler class and converts this class and the spell HUD class to static event handlers.
- Fixes the HUD position option which got broken in the previous spell HUD commit
