#23 Error registering EmptyArray<T> (Windows 8.1 x64)

[Daniel Santana]

Due to EmptyArray<T> that doesn't have a namespace (null), i changed Register in genericutil do support this.

    internal static void Register(Type t) {
        Dictionary<string, List<string>> nsmap = null;
        // dgsantana: Correct bug for EmptyArray that doesn't have a namespace defined... ????
        var _namespace = string.IsNullOrWhiteSpace(t.Namespace) ? "" : t.Namespace;
        mapping.TryGetValue(_namespace, out nsmap);
        if (nsmap == null) {
            nsmap = new Dictionary<string, List<string>>();
            mapping[_namespace] = nsmap;
        }
        string basename = t.Name;
        int tick = basename.IndexOf("`");
        if (tick > -1) {
            basename = basename.Substring(0, tick);
        }
        List<string> gnames = null;
        nsmap.TryGetValue(basename, out gnames);
        if (gnames == null) {
            gnames = new List<string>();
            nsmap[basename] = gnames;
        }
        gnames.Add(t.Name);
    }

I had the same problem with a type with no namespace. Here are the genericutil changes that solved it.
