Mention INotifyDataErrorInfo in WPF data binding overview

[ghost]

The validation section only mentions IDataErrorInfo, it should additionally or exclusively recommend its successor INotifyDataErrorInfo.
I had heard a recommendation of INotifyDataErrorInfo elsewhere but after reading this article i got the false impression that it isn't supported in WPF and wasted some time implementing IDataErrorInfo on my Viewmodels. Only when searching for more tutorials later I found one using INotifyDataErrorInfo and rewrote my code.
