My opinion:
1. text attack/original attribute/original race
These values should be loaded from cards.cdb
2. trap monsters
cards.cdb should keep the attribute/race of trap monsters,
so EFFECT_CHANGE_ATTRIBUTE in card_add_trap_monster_attribute() is not needed.
2. get_attack(),get_attribute(),get_race()
Now we can get the values of cards in LOCATION_SZONE,
so trap monsters can work well with all kinds of EFFECT_CANNOT_SPECIAL_SUMMON
