Apply a code formatter to rados-haskell

@christian-marie

I added the minimal stylish-haskell config I've been using to a branch and ran it over the **rados-haskell** sources. As code formatters go it's rather primitive, but if nothing else it tidies up whitespace and sorts imports, so I suppose it's worth something as a normalizer.

You may or may not like the result of what it did. If you do, great. If not, jettison.
