Add Persuade/Leadership Skill to Divine Champion

[Lansert]

For a class with a main ability, Divine Wrath, having a duration tied to Charisma and being so closely tied to other divine classes where Charisma is a main stat, Paladin and Blackguard, it seems odd that so few Charisma based skills, especially this one, are not a Divine Champion skill, especially because it is a class skill for every other divine class except Ranger. I think Persuade/Leadership therefor should be a Divine Champion class skill which it is not in vanilla NWN/Champion of Torm class.

Approved and expanded. Now that persuade is leadership and actually useful we will do a pass over all classes and decide which ones that currently don't have it should.
