- Added column "RequiredArrowType" to skill_require_db, set to 1 all arrow-based skills.
- Added support for ArrowType requirement on skills. It checks for having an item equipped on the arrow-slot who's view has to match with the required arrow-type (works the same way it does for weapons).
- Skills will automatically be ranged and arrow-types when they have a arrow-requirement.
- Skills will automatically consume arrows if used with a bow and the skill is an attack weapon-based skill even if the skill_require_db doesn't specifies arrow requirements (this is for stuff like backstab used with bows)
