"Log out" menu item

[Manu Cornet]

Hi !

Currently, the last entry in the "System" menu is called "Log Out %
user...", which is not accurate since the dialog also allows the user to
shut down the computer, reboot, sleep, etc.

My personal choice would be "Exit...", but I have heard other
suggestions as well :

* Exit session...

* Quit...

* Quit session...

* You name it :)

Should we find a way to include the username in the label (like the
current one) ?

Another question: the corresponding tooltip is misleading as well
(mentionning "log in as a different user), what do you suggest to
replace it ?

Thank you for your ideas :)
