New result 'JSONActionRedirectResult' in json-plugin
Adds new result 'JSONActionRedirectResult' to json-plugin. Contains tests
and example in showcase app. The new result type is intended to be used along
with existing JSONValidationInterceptor. It makes it possible to do form
validation via ajax and handle form submitting, action execution and redirect
evaluation all in one request inside JS context.
The sample Action is called `AjaxFormSubmitAction`. That example is by far
longer that the change to json-plugin itself (not just that action class but
other files that it requires). Here is an excerpt of it's javadoc, that shows
what can be done with the new result:
* Depends on `json-plugin`.
* Requires `jsonValidationInterceptor` to be on stack.
* Uses a special json redirect result type.
* Uses http parameters `struts.enableJSONValidation=true` and
`struts.validateOnly=false`.
* Uses a customized theme to make sure html elements required as error
containers are always present and easily selectable in JS.
* Uses some custom JS code depending on jQuery to issue AJAX request and to
render errors in html.
* Shows visual feedback while waiting for AJAX response.
