Add objects support

Needs to add objects support in `ts-repeat`

### Example

```js
$scope.data = {
  "123": { id: 123, name: "dave", age: 23 },
  "456": { id: 456, name: "chris", age: 23 },
  "789": { id: 789, name: "bob", age: 23 },
  "101": { id: 101, name: "tom", age: 23 },
  "102": { id: 102, name: "tim", age: 23 }
}
```
