[notif-center] group exact notifications into one box

[ildar]

it's no use having a line of notifications with the same text

Uhm... it's possible, I think... even with my convoluted approach in it. I'll add that to my goals for notification-center. But right now, my priority is to make the notification center scrollable^{i don't know where to start with this though.}

Guess if you group hords of same notifications, scrolling might not be needed )))

Well you have a point there. Okay, I'll prioritize this one over the scrollable notif center
