[arch-haskell] habs updates

[Peter Simons]

Hi guys,

the following commits updates a hand full of habs packages to the latest
available versions:

  http://github.com/archhaskell/habs/commit/78b2f329c3b2e5692a40832da3fce2f6c5ea6268

These files have been generated with the latest tool-chain, which comes
with several updates:

 * the original cabal name of every package is available as ${_hkgname},

 * the generated uninstall.sh hook uses --force to avoid warnings during
   updates,

 * packages provided by GHC are no longer listed as dependencies, and

 * our attribution header of choice these days is "Maintainer:".

I have tested the changes extensively, and everything seems to work
fine. If there is no objection, I would like to upload these updated
packages to AUR.

Take care,
Peter
