* Full duplex client

* Quik acts as server not client (this makes a lot of sense!) and is stable now

From tests:
// Multiplexing in action
// We access results asyncronously and do not wait
// for round trips to Lua and back on each ping
// Task.Result takes 43% and stream reader takes 7% (of 2x reduced time!)
// We are bound by Lua here
// Average time 500 msec per 5000 calls or 10 calls per msec or 100 microseconds per call
// Warmed up standalone profile takes on average 800 msec per 10000 calls, 12.5 calls per msec or 80 micros
// Quik is c.2x times slower
