[arch-haskell] Upgrading Yesod conflicts with JSONb

[Leif Warner]

I just commited an upgraded of Yesod and some associated tools to the
repo.  It's in a branch marked yesod_0.9, however, rather than master,
as it required deleted JSONb and data-object-json, which depended on
JSONb.
JSONb depends on an older version of attoparsec, and was holding back
other Yesod-related things that depended on the newer attoparsec.
JSONb hasn't been updated since March, and on it's Hackage page[1], it
says
"Have you considered aeson (http://hackage.haskell.org/package/aeson),
a newer, extensively benchmarked JSON parsing library?"
- which gives the idea that this package might be deprecated.

Feel free to merge in these updates if JSONb and data-object-json
won't be missed from the repo (at least for now).
