Notifications don't dismiss properly below android 4.3

Notification listener api isn't available, listens for notifications through the AccessibilityService but cannot detect when they are dismissed - temporary solution: remove all icons when the notification panel is opened.

I also need a way to tell if two Notification instances are for the same notification or not. Possible solution: pass a string id along with all notifications. Not sure what the id would be below 1.3 though...

It's probably not possible to detect this, however I'm leaving this open in case there is some extremely hacky solution somewhere that barely works but might get the job done. If I add a notification panel option in a future update that would make it a lot easier to detect when they have been dismissed since I will be the one dismissing them :D
