Newscaster and photo cleanup

Synthetics can no longer magically print color images using a black-and-white photocopier.
No longer possible for organics to acquire a synth-image by un-attaching it from a newscaster submission.
News articles now come with a timestamp and photo captions, if anything was penned on an attached photo.
Reception-checks no longer unconditionally sleeps the thread. Was causing havoc with NanoUI.

Misc. code refactoring.

I was just planning to add a timestamp, instead I accidentally the whole thing :frowning:
