The notification menu logic actually works. Yay. That means we've finally got an extensible notification system and can load arbitrary notifications of a given type into a popup (on demand), each with its own "view all" and "mark all seen". Now we just have to finish the json backends for the currently supported types and work them into the navbar. Might seem trivial or insignificant but this is a huge step forward. Online notifications are everything in an event driven world.
