Dto finally making it to server correctly!

* JsonHelper uses
System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Full in
settings, which is causing an error when trying to reference this from
service. So, service is now duplicating serialization/deserialization
code that is in JsonHelper (code in two places!! noooooo!) I have no
alternative at the moment. Live to fight another day.
* Dto is no longer a byte[] in ibDing, so going forward it will be
assumed the dtos are not necessarily byte[]'s.
* Sort of...I am not sure how this will affect the overall porpGib node
substrate stuff.
* Currently, the dto gets serialized and is passed via an
ibValue._(dto). I need to see if this works with other types in addition
to the current one (which is an ibDing with a dto of type
Dictionary<string, object>).
* Server-side deserialize code duplicates deserialize code in commonGib.
