Review request for Plasma.


Summary
-------

This delays creation of PanelView's until there is an actual screen for them. It also removes the views when the screen is removed.
That solves a few problems with panels that have all empty sizes and are thus not visible even though they are positioned correctly when a screen is plugged in.
This patch also removes a duplicate sanity-check and sets the size for panels to 100% if it is empty, so that panels which are saved in the appletsrc with a 0 size are visible again.

Testing
-------

Did a couple of iterations with starting and stopping plasma, as well as adding and removing my second screen. In between i changed the size of the panel and added/removed applets.
All changes were correctly saved and restored and it did not crash on me!! :-)


Thanks,
