AI Photography Extention #2

Gives the ability to take and view photo to Cyborgs

AI's share their photo album with connected Cyborgs, and connected Cyborgs have the pictures they take saved to the AI's album. If a Cyborg is not connected to an AI, photos are saved to the Cyborg's camera object. If a Cyborg has photos in it's album while not connected to an AI, but is subsequently connected to an AI, the photos are added to the AI's album. This is initiated by pulsing the appropriate wire on the borg.

Cyborgs can attach images to newscaster feeds, from the active album available to it (the AI's, or its own if disconnected)

Cyborgs cannot interact with photocopiers, but however have become a moving printer. They are every inefficent at printing, and thus can only print two color pictures before needing to be refilled with toner (simply click on them with toner in active hand).

Added some span classes to the previous AI photography work.

One minor bug fix to photocopier which could result in a photo object ending up in the 'hand' of an AI or cyborg.
