Add support for the device-manager module.

Currently this module only really allows for devices to be renamed, so we add a new
dialog that can be activated by right clicking on devices (i.e. sinks/sources).
This dialog allows you to enter a new name which will be set via the extension
provided by the device-manager module.

Future work will allow you to manage (i.e. rename, delete etc) offline devices too.
