Official Enchant Blade damage (fixes #975)

- Implemented the fully official damage calculation for this skill, it's now 100% accurate
** Partially reverted c3f4618
** The damage bonus is: [((SkillLv x 20) + 100) x srcBaseLevel / 150] + srcINT + srcMATK - tarMDEF - tarMDEF2
** The damage bonus from base level and INT is calculated when the status change starts
** The damage bonus from MATK and the reduction from MDEF/MDEF2 is calculated per hit
