All npc->Defense[] Defence Types

/*
Defence Types (Results/Outcomes) in the Engine for npc->Defense[index]

This list may, in the future, equally apply to Link->Defense[]

This list is split into five segments:
1. Implemented (old): These are in 2.50.0->2.53.0
2. Implemented (new): These exist only in 2.54, and some only exist in specific builds (and later).
3. Planned: These are likely to be added to 2.54, or 2.55.
4. Planned, Custom: A set of types that are used solely by scripts.
5. Insanity: In-dev discussion occasionally runs into InSomNia madness. These probably won't exist, but: Who knows, eh?

    indices '69' or '70'.
