This commit implements the new private browsign mode for rekonq:

- it implements a new KAaction in the Application class to trace changes on
- stops session management and save it, restoring last visited sites on restoring mormal mode
- implements necessary changes to iconmanager, urlbar & application

Please, note that the private browsing mode will definitely work just on KDE SC 4.6, cause of
the needed changes in kdewebkit to eg handle cookies and so on..
.
Hope you like it :)
