Add a helper class to avoid missunderstood using objects and variable params list

May this helper class should be discussed
Add a much more common alternative to format a localization with parameter.

new: string result = Localization.Format("Hello {0}", 4711);
old: string result = "Hello {0}".FormatLocalized(4711);

Both available, the old way is not common but you will think about …
This could be important, because any format string is a key and should be changed wisely.
