Support localized choices loaded from the web out of the box

[andrewtelnov]

Currently, if an item from restful API comes in the following format:

{ 
   value: "item", 
    title: {
          en: "item in English", 
          de: "item in Deutch"
    }
}

We do not recognize title object as a valid object and do not set it to the choice item text property.
It will be nice to support it.
