Automatic hearbeat using WS pings/pongs

[oberstet]

There should be an automatic heartbeat feature to quickly recognize broken connections.

This is an important one. Server-initiated WS ping/pong will only allow the server to detect broken connections quickly .. not the client. One needs client-initiated WS ping/pong in addition. You need both.

You don't necessarily need both. You just need the client to record the last time it received a ping from the server and have a thread that uses that as a timeout to kill the connection.

@william-ferguson-au interesting idea. could work. I guess I'd still call it a "workaround", but still. unfort., it won't work in browsers (unrelated to AutobahnAndroid, but relevant for AutobahnJS), because the W3C WS API doesnt expose any ping/pong (not receiving, not sending). anyway: we do want to have client initiated (and timed out) WS ping/pong in AutobahnAndroid v2 ..

I am working on this with some ideas, should have a solution soon. This should also deal with #36 and will ultimately pave way for #280
