Fix ticket #211 - Burning Ember Number

UnitPower() has a hidden 3rd argument to get the true value of a warlock's
secondary power value.  This fixes BurningEmbers() and SoulShards() to
return values from 0 to 40 (for the number of ember or shard segments)
instead of 0 to 4 (full ember or shard).  This also now correctly
correlates with the burningembers=xxx and shards=xxx values in warlock
script SpellInfo() lines.
