I'm not quite sure where to go with this code right now. It needs a little cleaning, but might not be bad for J8. It would only execute right now, for wpapsk formats, that have more than 1 salt, so 'should' be safe. But I will wait for instructions from others.

We have a third option of course: Apply the patch as-is, with "if wpapsk" in loader.c. I do not mind that at all for now. In fact we should definitely add it as-is to unstable/Jumbo-8 regardless of what we do to bleeding. So please post the patch!
