Added test that loads xaml with an explicit list. The official XamlReader can read it successfully but the own XamlParser fails and should be fixed.
Fixed parser so it can handle explicit lists.
Added xaml parser support for collections in attached properties.
IDictionary (and not just ResourceDictionary) is considered a collection and supported by own XamlParser.
