[1.20.4] Ref: Inline setting event functions

[emyfops]

This pull request changes the AbstractSetting event subscribers such as onValueChanged, onValueSet and others to facilitate subscription without having to wrap it in an apply block

Before:

private val mesh by setting("Mesh", true, "Connect similar adjacent blocks").apply { onValueSet(::rebuildMesh) }

After

private val mesh by setting("Mesh", true, "Connect similar adjacent blocks").onValueSet(::rebuildMesh)

Instead, we call apply in the event subscription event

fun onValueSet(block: (from: T, to: T) -> Unit) = apply {
    listeners.add(ValueListener(false, block))
}
