warlock changes

the warlock should be changed to an A-class with cha as the primary attack stat. they negotiate and bargain for their powers, so cha is appropriate.

fey should be cha, int (eladrin, gnome)
infernal should be cha, con (tiefling)
dark should be cha, dex (drow)

also, dark pact should have referred to the shadowfell, rather than to "the dark beings that lurk in the shadows of the drow civilization."

EDIT: the dark pact should be subsumed by the gloom pact.
