Merge lp:~cjcurran/indicator-sound/unify-device-handling-patterns into lp:~indicator-applet-developers/indicator-sound/trunk_3

[Conor Curran]

This is essentially a renaming refactor that was needed on the service side. Every since the voip item was introduced the existing pattern within the pulsemanager of assuming its userdata object was some sort of sink representative became untrue. The userdata mgr is simply just now a wrapper for which the pulsemanager uses to communicate with to menu. It is now called simply 'Device'
Furthermore all state should be stored in the respective widgets. Therefore there is no need for Device to calculate volumes etc.
