Update DDP support to latest specification #9
Description
JsonDeserializeHelper seems to only handle 3 message types "set", "unset" and "result".
The "result" message seems to work okay, but with Meteor 1.1.0.2 our .NET client is never seeing any "set" or "unset" messages, so data subscription is not working at all.
JsonDeserializeHelper should be updated to support all current DDP messages that can be expected to be received by a Client.
DDP specification can be found here: https://github.com/meteor/meteor/blob/devel/packages/ddp/DDP.md
