commit 8f85db2a32cab4bad987b2100424fbaf42f6ed26
Author: Thomas McGuire <mcguire@kde.org>
Date:   Mon Apr 25 00:50:43 2011 +0100

    Implement readOnly() for Akonadi kresources.
    
    Now it doesn't ask me if I want to save in my local calendar
    or in my Facebook folder anymore, since only the local calendar
    is writeable.
