Rename collections

@haz , maybe better here than email to keep it all contained and clean.

I suggest the collections are given more informative names. For example, `new-fond-papers` should become `fondsat`, as those were clearly designed in that paper.

Now `original-fond-papers` is more complex, I was reading your PRP paper and some come from FOND-IPC08 track:


And then some come from IPC06 and Little&Thiebeaux paper:


If anything at all I would call them all `prp`, but may be worth splitting them into exactly where they come from. And that doesn't mean we cannot have `prp` as well as many subcollections together.
