Add RuneType enum and DamageType.ANTISIEGE

RuneType covers the rune_type values in the client cache data
(CLASS, DISCIPLINE, RACE, TALENT). ANTISIEGE matches the
combat_attack_resist key in the cache data.

RuneTemplate.rune_type and combat_attack_resist on both cache
templates now use these enums.
