Changed: `console.dir()` to bypass inspect() methods

Given the following script:

```js
function User(first, last) {
  this.first = first;
  this.last = last;
  this._id = 12345;
  this._role = 'admin';
  this.inspect = function(){
    return '#<User ' + this.first + '>'
  };
}

function UserCollection() {
  var users = [];
  this.push = function(user){ users.push(user); };
  this.inspect = function(){
    return '#<UserCollection\n  ' + users.map(function(user){
      return user.inspect();
    }).join('\n  ') + '>'
  };
}

var users = new UserCollection;
users.push(new User('tobi', 'ferret'));
users.push(new User('loki', 'ferret'));
users.push(new User('jane', 'ferret'));

console.log(users);
console.log();
console.dir(users);
```

before this change you get the same output of:

```
#<UserCollection
  #<User tobi>
  #<User loki>
  #<User jane>>

#<UserCollection
  #<User tobi>
  #<User loki>
  #<User jane>>
```

not so useful, to make `console.dir()` more like the browser in that it's more representative of what the object really contains I think this would be a really useful switch, otherwise there's no way (AFAIK) to bypass potentially confusing `.inspect()` implementations. With this change you'll then get:

```

#<UserCollection
  #<User tobi>
  #<User loki>
  #<User jane>>

{ push: [Function], inspect: [Function] }
```
