support $href success callback triggered by $ok

[gliechtenstein]

How it used to work

The $href action was one way street. You open a new view using the $href action but once you do so, there was no way to get a response back from the next view

{
  "type": "$href",
  "options": {
    "url": "..."
  }
}

How it works now

Now the $href action supports success callback.

{
  "type": "$href",
  "options": {
    "url": "..."
  },
  "success": {
    "type": "$util.alert",
    "options": {
      "title": "Return Value is",
      "description": "{{$jason.name}}"
    }
}

In order to return a value from an $href transition, you close the view using the $ok action.

The $ok is similar to $back in that it goes one step back regardless of whether it was opened modally or as a push transition (in case of iOS).

However the $ok can return a value to the parent view using its options. In order to make the previous example to work, the second view should return its control back to the first view using the following code:

{
  "type": "$ok",
  "options": {
    "name": "Alexa"
  }
}
