* Added 'RequireStatuses' field on skill_require_db.txt
- This field value uses SC_STATUS (see db/const.txt)
- You may custom add more than 1 status required, example: SC_SIGHT:SC_ENERGYCOAT
- Removed some ST_ for 'e_require_state' list and move the value from 'RequireState' to 'RequireStatuses' field:
-- ST_HIDING -> SC_HIDING
-- ST_CLOAKING -> SC_CLOAKING
-- ST_CART ->SC_PUSH_CART
-- ST_SIGHT -> SC_SIGHT
-- ST_EXPLOSIONSPIRITS ->SC_EXPLOSIONSPIRITS
-- ST_CARTBOOST -> SC_CARTBOOST
-- ST_POISONINGWEAPON -> SC_POISONINGWEAPON
-- ST_ROLLINGCUTTER -> SC_ROLLINGCUTTER
* Fixed bugreport:8053, restricted equip should be put-off when player warped to restricted map (of the equip) if 'allow_equip_restricted_item' is 'no'
* Corrected db/const.txt value
- Added mf_skill_damage
- Sync some SC_STATUS with 'sc_type' on status.h
