minor changes needed for the next commit.

- BKE_add_image_extension now sets the extension rather then appending. (no more image.jpg.tga)
- py/rna functions which have no return value now raise an error if a non-None value is returned.
- added back the red-alert flag so buttons can have a red highlight if somethings wrong.
