initial client merged to https://github.com/niallyoung/goNDK v0.0.9 is up

I'll start extracting gift-wrap support and smash out an overdue update to event/ - branch will be up shortly, but give me 24h and I'll have a well-engineerd cli

(may not be 100% compliant on launch, but maybe out-of-the-box if we can find some samples / known-good test data, then PORT!)
