Unsubscribe from a topic

[om26er]

Currently there is no way to unsubscribe a topic. We probably need to implement that.

one use case for that is to conserve mobile data usage i.e. only receive events when required.

@oberstet thoughts ?

yeah, unsubscribing from a topic is sth that WAMP provides.

both ABJS and ABPy are actually returning a subscription object when subscribing, and use that to unsubscribe:
