Use other than toString in messages

In the verify message that shows expected arguments and actual arguments, 
toString() is used to show both the expected and actual arguments.  Some 
classes don't have a very good toString() method, which makes the message less 
useful than it could be.  

Need to investigate ways of supplying an alternative form of extracting a 
string from an object, when calling verify.  For example, maybe a variant of 
verify that allows passing a method for formatting arguments.  

Whereas there are cases in which an ArgumentCaptor could be made to do some of 
this, I think there are cases where an ArgumentCaptor wouldn't work quite so 
well.  I need to think about this some more.
