Unity: Force start background plugin

[Khurshid Alam]

If a user, already running a Gnome session upgrades or install unity by installing unity-session, background plugin doesn't start automatically (with u-s-d). This plugin has been removed from gnome-settings-daemon (Ubuntu carries a patch which only adds back the schema) and since gsd doesn't use it, it gets turned off.

The background plugin is necessary to sync background related settings (wallpaper, sound, messages) with unity-greeter. If it doesn't start with u-s-d, changing wallpaper will not change the background of unity-greeter.

The change was introduced in https://bazaar.launchpad.net/~unity-settings-daemon-team/unity-settings-daemon/trunk/revision/4179

This can be done in gsettings-override (In unity specific section)

[org.gnome.settings-daemon.plugins.background:Unity]
active = true

Merge should happen against https://code.launchpad.net/~ubuntu-desktop/+junk/ubuntu-settings

Since it's a +junk, I can't request merge proposals. I am also attaching the diff here.
