add a ccsm option to hide volumes in launcher

Bug Description

Add an option to compiz config's unity applet that warps the gsetting "com.canonical.Unity.Devices devices-option" (Never, Always, OnlyMounted=default one)

I don't think this needs design consideration; we don't expect the end-user to be tinkering around deep in CCSM settings, and even if they do, a simple setting such as this would be easy to understand.

This bug was fixed in the package unity - 4.6.0-0ubuntu1
