Addons [AddonsLab] Unread Post Count 1.4.3

Any other navigation tab can show the number of unread posts by configuring it to use a callback for the badge with class name "AL\UnreadPostCount\Callback" and method "getUnreadPostCount". This is the default setup for "What's New" button after add-on installation.

The badge is added using default XenForo 2.x layout/styling, but it can be easily styled for each case using CSS only by using "nav{navigationItemIdHere}" class.
