COMMITTED: SE_ImprovedSpellEffect

[Caryatis]

This is a pretty huge one for alot of servers I imagine. Tons of mobs make use of this spell(Spreading Stone) alone, let alone the new cleric Promised Renewal lines, etc.

The counterpart to this effect is SE_BossSpellTrigger(which is coming shortly), the key differences I can find are that ImprovedSpellEffects can land on any target and have single target effects while BossSpellTrigger effects can only land on clients and have PB AE effects.
