Split the pretty-printer out - pprint will now give you pretty much
anything you are likely to want to pretty-print as a String. For a Doc
you need (to_HPJ_Doc . ppr), which could be made nicer if it is widely
used.

Also took the opportunity to do a bit of module renaming and fixed the
odd typo here and there.
