Lukasz Gromanowski 594cc693b2 Fixes #1006: Many NPCs have 0 skill
Added calculation of skill values for NPC with mNpdtType
set to NPC_WITH_AUTOCALCULATED_STATS (their NPDT is 12).

* The Majority Multiplier is 1.0 for a Major or Minor Skill, or 0.1 for a Miscellaneous Skill.
*
* The Specialization Multiplier is 0.5 for a Skill in the same Specialization as the class,
* zero for other Skills.
