[Deskbar] New Volume Handler

A shiny new volume handler for you testing desires. It doesn't depend on
any new fancy stuff (read async). Just stick it in handlers/ and knock
yourselves out!


PS: I'm really sorry Raphael. This handler makes you network places
handler obsolete

PPS: The priorities of the handler needs to be fixed, but hey. Release
early release often!
