#450 fix race requirement support on SpellDamage

there was supposed to be some lua_race_id which is just silly, instead we will do the same design we use for quest kill requirements, check race, race type and base race type

SpellDamage arguments 7+ can supply a class or race id

SpellDamage(caster, type, min_damage, max_damage, crit_mod, no_calcs, class/race_id, ...more class/race_id)

This should allow for support of spells like Fury's Tempest which has specific racial damage

heres my updated script for Tempest which is working as expected (does racial damage after initial damage) -- will require a code update to fix the lua SpellDamage to properly check race id values

funny enough we don't have any elemental mobs described in our race_types table or anything else so I just created a spawn to test this with. Content team has some work to do with race types for elementals :D
