Insomnia Notifier

Checks if phantoms can spawn, and shows a fake client-side effect in the inventory.

The effect is only shown in the Overworld.

It only checks that you haven't lied on a bed for 3 Minecraft days, without checking that you have direct skylight access or are at Y>64.

Friendly reminder: You don't have to sleep. Just lie on a bed for a moment to prevent Insomnia.

Known issue: it doesn't check the doInsomnia gamerule, since it's a client-side mod, not aware of gamerules.
