* aspell: hacked up a little patch to allow additional dictionary

directories to be specified through the environment variable
  ASPELL_EXTRA_DICT_DIRS.  This way dictionaries don't have to be
  installed into aspell's prefix.  Instead you can just set
  ASPELL_EXTRA_DICT_DIRS to $HOME/.nix-profile/lib/aspell and install
  dictionaries separately with nix-env (e.g. "nix-env -i
  aspell-dict-nl").
  
* Added a bunch of Aspell dictionaries.  Additional dictionaries can
  be added easily in development/libraries/aspell/dictionaries.nix.
