Wacomtablet moved to kdereview

[Jörg Ehrichs]

Hi Aaron,

thanks for the long review. :)
Most things are implemented now.

But I have a few questions left.

Is there any example I can have a look at on how to implement this?
api.kde.org has just a few things about the HotPlug Engine, but it does look 
more like that it is connected to solid which isn't implemented for my case 
"yet".

I'll try to get a <type> for the tablets working into solid, this was on my 
TODO list anyway. :)

It was the first time I used the plasma part and for my the actual applet was 
just the part visible to the enduser. That's the reason it ended up the way it 
is now. :)
