Title: Refactor scratchpad and related videos into separate files

@dmnd @spicyj @divad12 this is mostly a minor change (and will require modifying packages.py in any case), but since all of you guys have some vested interest in all these modules, i thought i'd ask just in case you think that pulling these out of khan-exercises is particularly problematic for any reason.
