Ability to extend XenForo_NewsFeedHandler_User

[Sniper]

I'd like the ability to extend the XenForo_NewsFeedHandler_User class.

The reason I ask is because I've introduced a new field in the users table, I got it working perfectly by editing the XenForo_NewsFeedHandler_User and added a new _prepare method.

But if I wanted to include it in a addon I'd have to create a custom handler to display the feed, seems like a lot of work compared to adding a new method to the XenForo_NewsFeedHandler_User class.

Thanks
