* Refactor cult dagger rune drawing and null rod rune clearing into components + minor rune / blood magic tweaks (#62918)
The act of inscribing runes, anchoring / unanchoring cult structures, deconstructing cult girders, and purging cultists of holy water have all been moved off of the cult dagger itself and onto a component, cult_ritual_item.
The act of destroying a cult rune or heretic rune with the null rod have been moved off of their respective items and onto the nullrod itself.
Added a signal, COMSIG_ITEM_ATTACK_EFFECT, for the above purposes.
Various cult spells and dagger interactions have had their code improved slightly.
