* Move the composition of Haskell packages out of all-packages.nix

into haskell-packages.nix, which depends on an instance of GHC.
  This allows a consistent set of packages to be built with the same
  GHC.  For instance,

  $ nix-build -A haskellPackages_ghc683.xmonad

  builds xmonad and all its dependencies with GHC 6.8.3, while

  $ nix-build -A haskellPackages_ghc6102.xmonad

  does the same with GHC 6.10.2.  This is the same technique used with
  kernelPackages.  It also means that we don't need things like
  "cabal682" and "cabal683" anymore.

* The setup hook is now in a separate wrapper package so that we don't
  have to recompile all of GHC every time we want to make a small
  change.

* cinelerra: this package appears to have an accidental dependency on
  the "X11" Haskell package.
