After testing with some real-life data I take that back. I got a very 
significant boost even for some sets of salted hashes I had archived. I 
am amazed how some people manage to misuse a perfectly good sized salt.

So here it is, suggested for the Jumbo. This patches all formats that 
had only three sizes (except AFS), extending them to have five.

The bunch of formats that does not have *any* hash functions, are not 
fixed here. I suppose some of them should be looked at - especially 
unsalted ones like mysql. But that is an ancient type of mysql, isn't it?

Many of the formats in this patch will not likely ever benfit from the 
larger sizes but I can't see how this would ever do any harm either.
