More info when serialization fails

[benrhughes]

This project looks really interesting, but when I try and use it against a real-world object tree I (understandably) run into some issues - for example that System.Type can't be instantiated. That's fine, but it would be very helpful if the exception could include the class that the property appears on so that I can add the ignore tag or otherwise work around it.

Cheers,

Ben
