Vue: vm.$watch on a specific property of objects in an array

[tianhai82]

Feature request.
It will be useful and efficient to watch on a specified property of objects in an array. For example,
...
data: {
users: [{id:1, name:"peter", age:16},{id:2, name:"John", age:18}]
}
...
vm.$watch('users.name',function(newVal, oldVal){
// newVal and oldVal should return the particular user which name changed
},{deep:false}
);
