Edited Issue: Add WPF 4.5 support with CallerMemberName attribute [260]

There are only 5 or 6 lines of code to insert to produce a more easy and performant way to use notification.<br /><br />[CallerMemberName from Silverlight & WPF 4.0]<br />http://trelford.com/blog/post/CallMeMaybe.aspx<br /><br />Also notice that the .NET 4.5 MSDN sample now also uses this method for the implementation of the INotifyPropertyChanged interface:<br /><br />http://msdn.microsoft.com/en-us/library/system.componentmodel.inotifypropertychanged(v=vs.110).aspx<br /><br />thanks <br /><br />Frank
