Merge ~rs2009/unity:master into unity:master

[Rudra Saraswat]

This merge proposal removes indicator-messages as a recommend of unity-services, as it is notorious for causing crashes on Ubuntu Unity (reproducible with the live ISO too).

It also moves indicator-notifications to unity-services (it was a recommend of Unity earlier, and is now with the other indicators).
