Hwyla

Version 1.8.24:

- Properly blame mods who are returning a null ItemStack in getPickBlock.
    - This is completely invalid behavior and I will no longer tolerate being blamed for the crashes it causes.
    - Example blame: `minecraft:cobblestone from mod Minecraft returned a null ItemStack in getPickBlock(...). Please report this to them.`
- Fixed tooltip width calculation not taking fully formatted ITextComponents into account
    - Bold lettering spilled out of the tooltip since it's wider than normal text.
- Wrap Waila style plugins in our own plugin system to bring everything closer to the same codebase.
