v0.1.6

• Disconnection now removes nodes from internal store - they should no longer be found by .connectTo() calls on their ID.
• Changes to disconnect events so that they only fire ONCE per connection.
• Channels can now call conductor.rejct(id, reason) to reject a connection in progress.
• Removal of unnecessary debugger keyword when setting event handlers.
• connectTo() calls will now timeout - defaults to never, but can be user configured to reject after a given time.
