Review request for Plasma and Alessandro Diaferia.


Summary
-------

The state calsses now have less functions. Only one for connections and one for configuration. The first one is only called once at PMC initialization, the second one is called at each state switch. Some connections can conflict between states. Those are connected at entry() and disconnected at exit(). Thanks to Alessandr's work we can now also configure the layout from within the state class (I only had to correct some namespace stuff in the medialayout class, I hope that was correct).
This patch also gets basic functionality back. The modes are not really useful yet. Video mode is the most complete and can be used to view everything at th moment.
Next step: Clean this up a bit
Think about subclassing plasma widgets to get the widget type into the widget. This is necessary to be able to tell the controller to layout into zones.
Start work on information bar.

Testing
-------

Lots and lots. Seems to be quite slow, but I think that is a problem in the player. It always iterates over all the queue even if it should only show a picture.


Thanks,
