NOTE for OpenNotifier on iOS 5+: no support for pseudo-badges yet.

Whenever you get a "like" or a comment, you get a notification of this on your device, but no badge. OpenNotifier offers pseudo-badges and this makes it possible to disable the pop-up notification and still be notified. That's where these icons come in: after setting the pseudo-badge, you can select this new icon and BAM! You get a fancy little notification icon whenever you normally would've gotten a popup!

Have fun!
