New Spell/Item Affects

// the goal:
// create a generic way to treat both aff's and apply's as one thing
// if a spell does an apply and an affect, they become multiple modifiers
// if an object has a perm-affect, it just looks like another apply
// Maybe- spells redesigned into a list of modifiers, and if an item
//     has a modifier that's just a spellnum with flag == -1, then it
//     applies that spell to who wears it!  genius!
