Created CultureDictionaryFactoryResolver for use in the new MVC views which returns a ICultureDictionary.

This allows us in the future to use any type of data source for the dictionary. Have obsoleted the old
ICultureDictionary in the macro engines project (where it doesn't belong anyways). The new one doesn't expose
the 'Language' property to the front-end because this is a business logic class which means designers can just delete
a whole language from the db by calling 'Delete' on the object !
