Remove Lubuntu notifier and replace with Xfce's

Replace Lubuntu's notification system with XFCE's, which won't queue up your notifications, like the default one does. To do that:

sudo apt-get install xfce4-notifyd
sudo apt-get remove notification-daemon

When doing it this way, it shouldn't ask to remove all those extra packages, as there will still be a notification system in place. I think it will still say it is uninstalling lubuntu-desktop, but that is because it is a meta package, meaning a package of packages. It won't remove your desktop. :-)
