Symbol-keys are ignored when using pair events

[mistadikay]

Hi there,

just noticed you've added Symbol support. There is one bug though when using pair events like this:

myEmitter.on({
  myEvent1: function(e) {  },
  myEvent2: function(e) {  }
});

Since Symbols can not be enumerated with for ... in or Object.keys(events).on they are just being ignored in such cases.

Sorry, I don't have time for a proper PR, but here is a possible solution

// instead of using `for ... in` you can process each key type individually

// Symbol-keys
Object.getOwnPropertySymbols(events).forEach(function(event){
     // this.on/off/etc....
});

// String-keys
Object.getOwnPropertyNames(events).forEach(function(event){
     // this.on/off/etc....
});

Thanks @mistadikay. I'll try to fix this in a near future.

Hello @mistadikay. The last commit should have fixed the problem. I am releasing a 3.1.1 very soon.
