NullReferenceException when adding a null entry to the struct

 Traceback (most recent call last):

System.NullReferenceException: Object reference not set to an instance of an object.

When I use the Cook Computing NuGet package I don't get this error. Of course, we can't use that if we want a cross-platform application :-(

As far as I can tell, this issue occurs because XmlRpcStruct was modified from the original Cook Computing source code to use a HashTable instead of a dictionary.

This fork is based on XmlRPC v2.5, not v3 as Cook never marked it stable. I will take a look this week-end.

Thanks for the diff.
