Code review comment for lp://staging/~jbicha/onboard/dont-autostart-in-gshell

Actually, this doesn't work. Only the first AutostartCondition is being used. GNOME Shell & GNOME Fallback should use different XDG_CURRENT_DESKTOP values instead of the "unless-session" hack. For Oneiric, I guess screen keyboard users will have to just manually close onboard (which is easy to do).
