Allow to specify one handler for multiple events in the event bus reciever

[thibaultponcelet]

Allows to define set the same handler for multiple events with a simple syntax:

this.eventBusReceiver.onEvents([
      "an event", 
      "another event",
     ...
    ], function(event, callback) { /* Do something */});
