Boxee running via --standalone switch changes <shutdownstate> in guisettings.xml

When boxee is launched with the --standalone switch, changes <shutdownstate> to 1 in ~/.boxee/UserData/guisettings.xml.
This makes the function XBMC.Shutdown() to actually shutdown the system instead of quit boxee: The problem is that the next start of Boxee, even if not with --standalone, doesn't restore the value to 0 (and on exit will shutdown again the system).

Reproduction:
 1. Open boxee with --standalone argument
 2. Exit from boxee (this will shutdown system)
 3. Restart boxee without --standalone argument
 4. Exit (should shutdown again)

Thank you,
Eugenio
