Adapt to changed GetTalentInfo() to properly update talents.

GetTalentInfo() changed the parameters taken to:

    GetTalentInfo(tier, column, talentGroup [, isInspect, inspectedUnit])

and the returned values to:

    talentID, name, iconTexture, selected, available

Add placeholder constants for the number of talents, tiers and columns to
sanity-check iterating over all of the talents in the active talent group.
