Widget ajax broken for non-logged-in users

[boonebgorges]

Since switching to admin-ajax.php for ajaxurl in BP 1.6, the distinction between wp_ajax_ and wp_ajax_nopriv_ hooks has become relevant. For most BP core AJAX, this is already taken care of: in the Dashboard, the user is always logged in (so you only need wp_ajax_), and on the front end most stuff is taken care of by bp-default's AJAX handlers, which are hooked to _nopriv_ in the appropriate cases. However, the handlers for the Newest | Active | Popular AJAX in the Groups and Members widget was never changed over.

Fix coming up.

(In [6261]) Fire widget AJAX handlers on wp_ajax_nopriv_ actions, in addition to wp_ajax_

This ensures that the group and member widget AJAX continues to work for
logged-out users when ajaxurl points to admin-ajax.php.

Fixes #4464
