how to do this is going to be the big trick in all of this. the d-bus 
interaction is actually pretty simple, but preserving backwards compat will be 
interesting to accomplish.

we have KSystemTrayIcon which IsA QSystemTrayIcon. so even if we implement the 
D-Bus protocol in KSystemTrayIcon, we'll always have a QSystemTrayIcon, and 
therefore a regular system tray icon, as well.

what we really want is an API that takes the various possible information 
(icon, name, tooltip, etc, etc) and internally decides whether or not to use 
the D-Bus route or to use a KSystemTrayIcon internally and provide the other 
fun bits (e.g. the tooltip) "manually".

so this seems to indicate that we probably want a new class that will 
eventually end up in libkdeui. it should have a name that doesn't include 
"SystemTray" in it, and it should be source compatible as much as possible 
with KSystemTrayIcon so that it can be used as a drop-in replacement or as 
close to a drop-in as possible.

KNotificationIcon? meh.

that's cool with me. for now, let's put the kded plugin in with the systemtray 
widget. when it gets accepted as an official KDE bit, we can move it somwhere 
else, though i think it should remain in workspace and only get started when a 
KDE desktop session is being started.
