DeviceManager: Allow user to configure desktop device

Show desktop device in the Devices options page. Allow user to configure the port range for the desktop. These ports can then be used by others such as QML Debugger. Change-Id: I8c4a96207e54f58d1e9bc18c417cb378dc9f70c2 Reviewed-by: Christian Kandeler <christian.kandeler@digia.com>
