I may have got a bit behind with version control. A lot behind, in fact. Maybe I'll go back and split this sometime - then again, I probably won't. But hey, at least it's here!
- 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
- Adds new generic spell superclasses which aim to group spells such that duplicate code is eliminated, and functions standardised, as much as possible.
- Removes numerous spell classes which are no longer required as a result of this change, and replaces them with instances of the relevant generic spell classes.
- Changes the remaining spell classes to fit with the new system, mostly by having them extend the generic spell classes.
- Completes the transfer of particle spawning to the ParticleBuilder system.
