[Haskell-cafe] idea: ratings (or maybe comments) for packages in hackage

[Dan Burton]

And these steps are done!

* Download count is already there on Hackage, though it's relatively new so
it may take some more time for these numbers to have real weight.
* Revdeps are calculated and provided here:
