Merge patch by plfiorini :

Some changes to the API for notifications.
	* Don't go through be_roster to send a notification, but use Notification->Send() instead.
	* Rename App to Group to make the purpose clearer

And some changes to the notification code itself:
	* Use the Notification class as the way to convey informations about a notification. Allows easier extension of this class
	* Code cleanup
	* Use of the layout kit for the notify window

Unfortunately, the latter part clashes quite a bit with the changes I already did to the notification window, so it's now quite broken. Working on that next, but I wanted to separate that work from the patch ...
