Enterkey is broken on dialog 'OK'/'Cancel' button

[garry.yao]

It's not able to trigger buttons' click behavior with 'enter key' in trunk.

Regression of [4165] from #4269.
Where the default behavior( expected one ) was canceled.

Update the TC from the regression ticket: ​http://ckeditor.t/tt/4269/1.html.

Looks good... can we just have a more consistent naming? "stopBubble" is a mixture of "stopPropagation" and "cancelBubble" :)

Also, we're using a different convention for the attribute name and the method name here:

if ( stopPropagation )
    this.stopBubble();

At this point, let's just call it "stopPropagation", which is also a well known name.

Fixed with [4352].
