The most obvious deficiency of the original code is while it had some good effects, they were transient only - you couldn't save them.

I thought implementing this would be tough, but looking at camera.c, and copying code from just a couple functions, and a few variable definitions, it was easier than expected.

The `docamname()`, and `s_camgrab`, `s_camwait` and `s_camquit` case blocks, were all that were needed.
