Task #368: Move system tweaks to packages
lxlauncher-session-logout should translate the window message
When quitting an lxlauncher session, the prompt in the dialog window is defined in the file
/etc/default/lxlauncher-session. Its text cannot be translated, it must be rewritten each time the language is changed. A solution is to specify in this configuration file an optional gettext domain in which the logout script would be able to get translations.
