possible EventEmitter memory leak

[adamantivm]

I am getting warnings from EventEmitter about possible memory leaks.

To reproduce, open the prototype, pick a robot, click on the outlet to navigate to it and then click Plug robot in.

It throws a "(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit." with a corresponding stack trace pointing back to Robot.plugIn where it does action.execute().

It may be that action.js is not unsuscribing events from the underlying library after the result is received?
