[Change] Automated wizard spell indexing in spellbook

[Kubius]

Pretty much what the title says - instead of manually defining each and every spell addition, spellbooks now automatically detect all appropriate uplink entry datums and add them. General quality of life thing, but particularly useful for prototyping - with this change, work in progress spells can be swapped in/out using only a .dm with the spell and uplink entry.
