option to write images to a files on single frame renders, this isn't accessed by the UI at the moment, but could eventually be used for saving test-renders.

The main reason to have this is so renders can be scripted to write to a specific file without having to do annoying tricks like set a dummy start/end frame range, render an animation and work out the current frame image will be written to, then rename after rendering.

Also made some 'char *' args into 'const char *'
