Add for review and hopefully ready for KDE 4.2.
This applet tests and connects to various DBUS interfaces of messaging apps (yes parts might be needed to port to Decibel (Kopete DBus interface) for 4.2).

It is nothing special, but very useful to me, since I don't need to unlock my screen to see if there are new messages. It keeps the privacy by only notifying about a changed message status but nothing more.

Issues:
* Layout is done in a big function which repeats code for every interface. It might be possible to do this better.
* DBus usage might be improvable.
* Currently the counter starts when the screen is locked. So if you go away, get messages in the time between being idle and screen lock, you won't get notified.
This is, if it is desired, fixable with a small kded module loaded on startup and tracking changes for each app combined with a dbus connection to kscreensaver.

Maybe Decibel can give similar features (like showing all messages of the last 10 minutes).
