Wizardry Refined: Fix prerequisites, TL and VH vs H (#241)

Some prerequisites in the Wizardry Refined Spells Library were impossible, so I went through all the spells in the library and changed them to match.

There's a lot of changes, but they broadly fit into the following categories:

* Change prerequisites from their GURPS Magic version to their Wizardry Refined version.
* Change prerequisites where they seem to be incorrect (the same in GURPS Magic and Wizardry Refined).
* Drop Magery requirements that are removed in Wizardry Refined (for mysterious reasons; those might be a mistake in Wizardry Refined, but I did this for all of them except Steal Dexterity, Steal Might, Steal Vigor and Steal Wisdom, because I could see a way they accidentally overlooked those).
* Fix spell difficulty.
* Untick "Requires TL" from Technological spells and leave a note for how more complicated machines are affected (as per Sufficiently Advanced Technology, Pyramid 3-60 page 6).
* Left a note on Delay, Hang Spell, Link and Reflex that the number you can have "on" is limited by Magery (as per Contingency Plans)
* Removed some Enchantment spells that were in the spell library.

The full list of changes are:
* Alter Visage requires Perfect Illusion and 8 Body Control spells
* Animate Machine follows the "Sufficiently Advanced Technology" rule on magic
* Beacon only assists Plane Shift
* Cloud-Vaulting depends on Cloud-Walking instead of Walk on Air

* Malfunction follows the "Sufficiently Advanced Technology" rule on magic
* Move Terrain is IQ/VH (this should also be true of GURPS Magic)
* Mud Jet may also be satisfied with Water Jet and Create Earth

* Plane Shift requires Magery 2

* Preserve Fuel follows the "Sufficiently Advanced Technology" rule on magic

* Purify Fuel follows the "Sufficiently Advanced Technology" rule on magic

* Reverse Missiles deflects instead of reflects missiles that do more than 1d per level of magery
* Sanctuary depends on IQ 13+, Plane Shift Other, and spells from 10 different colleges

* Zombie requires Share Energy instead of Lend Vitality

Steal Dexterity, Might, Vigor and Wisdom in Wizardry Refined lose their dependency on Magery 3, but that's more obviously an oversight than other changes so I didn't change them.
