// If the system tray gets destroyed, the system tray
// icons automatically get unmapped, reparented and mapped
// again to the closest non-client ancestor due to
// QXEmbed's SaveSet feature. Unfortunatly with kicker
// this closest ancestor is not the root window, but our
// decoration, so we reparent explicitely back to the root
// window.
2. Removed popupinfo feature for now. The feature is a great idea, but the
implementation was too much copy&paste and code duplication with the
tab box. Plus it was buggy (no vertical center alignment) and contained
many unused codelines.
3. Fixed and simplified the session management handling (thanks to
KSessionManaged in libkdecore). This way we actually get a proper
discardCommand generated by KApplication, something that was missing
previously.
