Skill Database cleanups (rathena#4902)

* When reloading the skill_db clear out Abra, Magic Mushroom, and Reading Spell Book databases as well.
* Fixes NC_SHAPESHIFT and NC_REPAIR checking an invalid ItemCost slot based on the old implementation.
* Updated a lot of references to the old skill databases.
