GetSpecialization is nil on WOTLK-Classic

[KevinTyrrell]

The API function GetSpecialization is nil on WOTLK-Classic, causing Outfitter:TalentsChanged() to encounter an exception.

function Outfitter:TalentsChanged()
    self.CanDualWield2H = self.PlayerClass == "WARRIOR" and GetSpecialization() == 2
end

This then seizes the entire addon, causing little to no features to remain working.

Solution:

Current function

function Outfitter:TalentsChanged()
    self.CanDualWield2H = self.PlayerClass == "WARRIOR" and GetSpecialization() == 2
end

Modified function

function Outfitter:TalentsChanged()
    self.CanDualWield2H = self.PlayerClass == "WARRIOR" and select(5, GetTalentInfo(2, 24)) > 0
end

GetSpecialization appears to be retail function where you obtain Titans Grip simply from specializing yourself as 'Fury'. Instead in WOTLK Classic it appears you will just need to check the talent. TalentsChanged by the way is a very poor name for this function, but I understand much of this codebase is legacy.
