Igor Minar 35125d2513 refactor(toJson): use native JSON.stringify
Instead of using our custom serializer we now use the native one and
use the replacer function to customize the serialization to preserve
most of the previous behavior (ignore $ and $$ properties as well
as window, document and scope instances).

/**
* @ngdoc directive
* @name angular.module.ng.$compileProvider.directive.ng-model
*
* @element input
*
* @description
* Is directive that tells Angular to do two-way data binding. It works together with `input`,
* `select`, `textarea`. You can easily write your own directives to use `ng-model` as well.
*
* `ng-model` is responsible for:
*
* - binding the view into the model, which other directives such as `input`, `textarea` or `select`
* require,
* - providing validation behavior (i.e. required, number, email, url),
* - keeping state of the control (valid/invalid, dirty/pristine, validation errors),
* - setting related css class onto the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`),
* - register the control with parent {@link angular.module.ng.$compileProvider.directive.form form}.
*
* For basic examples, how to use `ng-model`, see:
*
* - {@link angular.module.ng.$compileProvider.directive.input input}
* - {@link angular.module.ng.$compileProvider.directive.input.text text}
* - {@link angular.module.ng.$compileProvider.directive.input.checkbox checkbox}
* - {@link angular.module.ng.$compileProvider.directive.input.radio radio}
* - {@link angular.module.ng.$compileProvider.directive.input.number number}
* - {@link angular.module.ng.$compileProvider.directive.input.email email}
* - {@link angular.module.ng.$compileProvider.directive.input.url url}
* - {@link angular.module.ng.$compileProvider.directive.select select}
* - {@link angular.module.ng.$compileProvider.directive.textarea textarea}
