Copying over kernel message dispatching from SN.  Using SN akka system, rather than the play akka system.  Which is now throwing a shit-load of other errors, so I gotta deal with that.
Rewriting message dispatch in Kernel to not expect a header because some sort of security cookie comes over all websocket channels, so need to be able to ignore that silently.
Commenting out Observable instantiation because it was fucking some shit up.
Formatting changes to notebook template to make it easier to read
Turns out I was totally screwing up how kernel requests were gettig handled, so copying/pasting in the right implementation.
