Spell Totems, AE conversion into REs

New Spell Totems allow us to leave persistent Radius Enchantments
anywhere we wish. These invisible objects propagate spell effects in a
radius around themselves until they expire. For simplicity's sake, I
created an "Old Style AE" setting that will ignore range checks and 100%
simulate current Area Enchantments - but with our new checks and
conditionals tech to eliminate mule abuse.

Spell Totems can also be used to create AE effects in an area of any
shape or size. For example: perhaps dark angels have a Darkness aura
around themselves, or perhaps going near the giant statue in Avar
Village brings you in range of a Killing Fields aura.

As three test cases, I have converted AMA, Truce, and Killing Fields
into persistent REs. I did not modify what they do, instead opting to
completely simulate old AEs for now. Truce, has, in fact, been restored
to its old functionality - both PvE and PvP. The spell is much smoother
with the new conditionals, and should no longer pose a mule problem.
It can be used to protect angeled mules, allies, and guildmates, as
well as prevent enemies from attacking you, but otherwise unaffiliated
whites cannot prevent you from fighting mobs or attacking other players.
