Load Experience values from settings files

[Grauenwolf]

Currently it is hard-coded in this block:

        //Check for ranks
        switch (name)
        {
            //TODO: Load Experience values from settings files
            case "Novice": return true;
            case "Seasoned": return ignoreRank || Experience >= 20;
            case "Veteran": return ignoreRank || Experience >= 40;
            case "Heroic": return ignoreRank || Experience >= 60;
            case "Legendary": return ignoreRank || Experience >= 80;
        }
