DoudouLinux CD

There is no visual difference between a DoudouLinux system launched without persistence, a DoudouLinux system launched with persistence but without persistence media and a DoudouLinux system launched with persistence and with persistence really active.

It would be nice to add an icon in the panel to notify this status. We could use something like a floppy disk icon which is red, orange or green. A click on it should show a balloon with the persistence status:

• system launched with or without persistence
• persistence media found or not

Maybe this could be highlighted later with a text and/or an icon in GDM or in LxLauncher. Of course if a persistence media is found, it's understandable name should be used, not an awful /dev/sda1 or F:\ ;-) !
