Truce, AMA, Winds, Sandstorm fixed

These four major Area Enchantments have had their safety issues fixed.
If these spells do not apply to you because of a safety check, you won't
see them at all, and you won't be able to discord them.

* Truce has been returned to its old functionality that everyone has
been longing for. If you cast Truce in a room, it will affect your
Guildmates, your Allies, Angeled characters, and your Enemies. Truce
prevents attacks between two players who are both Truced, and between a
monster and a Truced player. The notable exception is that Truce will
NOT affect unaffiliated white players. You cannot interfere with combat
from a guilded white. To affect an unwilling player with Truce, he must
be your Enemy, either by war, soldier, or you turning off your safety
and going orange. Innocents are affected by Truce so that players may
help them do quests. Any player affected by a Truce spell will be immune
to wall elements (so you can help your guildmates out of a trap).

* Anti-magic aura works exactly the same way as before, except it now
has safety checks. AMA will only affect your Enemies and Guildmates, and
will turn you orange if you turn off your safety and 'hit' an innocent.

* Winds and Sandstorm will only affect your Guildmates and Enemies, and
will turn you orange if you turn off your safety and 'hit' an innocent.

NOTE: Discordance will only remove these spells if they are affecting
you! Unaffiliated players cannot use these spells against you, and
neither can they discord them!

TL;DR: no more guilded whites interfering with war and shields.
