What:
Add toggle for compounding bonuses for lifetap heals.
Why:
When spell damage and heal amount bonuses are scaled to ludicrous
levels, this double dip results in very high heals from
relatively weak lifetaps.
Created new rule: Spells:CompoundLifetapHeals
If true (default):
Apply spell damage bonuses to lifetap damage
Pass that amount through heal bonuses
Heal for this resulting amount
If false:
Apply spell damage bonuses to lifetap damage
Heal for this resulting amount
