The F3 key 'save rendered image' made inconsistant choices to save either
in jpg or tga, when the output panel was indicating to render to movies.
Even worse, it was sometimes saying 'save jpg' and saved a targa!

Made it consistantly save .jpg now, since tga isn't a good common format.

Forgot to commit transform.h for previous bugfix in transform numeric input
