Review request for Marble.


Summary
-------

For the Satellites plugin I need a way to remove every item from the model each time the datasets are downloaded. This patch shows a buggy way to do so. It leads to crash when clear() is called concurrently with AbstractDataPluginModell::items(), for example because of a paintEvent(), see the backtrace at http://paste.kde.org/111817/
I can't seem to find a good way to fix that without introducing locking.
