Add xhr object to callbacks

To handle headers in Wiselinks callbacks (javascript events) I have added xhr in callbacks for page:fail, page:redirected, page:done. The xhr in the callbacks can be very useful.

Example

$(document).off('page:done').on('page:done', function(event, $target, status, url, data, xhr) {
  message = xhr.getResponseHeader('X-Flash-Message');
  type = xhr.getResponseHeader('X-Flash-Message-Type');
});

Javascript Events

1. page:done ($target, status, url, data, xhr)
2. page:fail ($target, status, url, error, code, xhr)
3. page:redirected ($target, render, url, xhr)

Add additional header X-Wiselinks-Target

The target, if used in the link or form, gets included in the header data and can be retrieved with request.wiselinks_target in the controller.

Add additional header X-Wiselinks-Scope

The scope, if used in the link or form (data-scope=), gets included in the header data and can be retrieved with request.wiselinks_scope in the controller.
