Merge lp:~khurshid-alam/unity-settings-daemon/fix-airplane-switch into lp:unity-settings-daemon

[Khurshid Alam]

Fix airplane mode switch not appearing on network panel.

[Sebastien Bacher (seb128)]

Indeed, from the build log 'warning: undefined reference to `gnome_settings_get_chassis_type' ... it's annoying that such problems don't fail the build :/

Thanks for the fix, it makes sense

review: Approve
