Form Serialization Wrapper is Incorrect

[shrunyan]

The instructions which show setting up the return value for the serializeArray is incorrect. Currently it tries to get a name property from the form element. Like so;

var wrapper = {}; 
wrapper[form.name] = data;

This is incorrect because the form does not have a name property and does not match the intention of the API, which expects JSON with a string literal property of form is submitted. e.g.

{
   "form": {...}
}
