Subject: [PATCH 4/4] camera-device-monitor: Don't add NULL devices to the
 camera list

cheese_camera_device_monitor_set_up_device() will return NULL for non
video devices (ie vbi & radio devices). Emitting the added signal with
such a NULL device, causes it to get added to the camera list, which later
on causes cheese to crash.

This patch fixes this by not emitting the added signal for non camera devices.
