Subject: [PATCH 33/35] cheese: Fix updating of device selection combo
 sensitivity on hotplug

If one started cheese with 1 device, and then added a 2nd, the device selection
stayed inactive, making it impossible to select the 2nd device.

This fixes this, and also makes the combo go insensitive again when going from
>= 2 devices to <= 1 device.
