Eelco Dolstra c68c95d55a Provide O(n) time implementations of fold/foldl/any/all
Previous implementations were O(n^2) because tail takes O(n) time.

Eelco Dolstra 6408a6a6fd * Trivial function to create a singleton list. Can reduce unnecessary
indentation in expressions like

    environent.extraJobs =
      [ { name = "foo";
          job =
            ''
              bla bla
            '';
        }
      ];

  which becomes

    environent.extraJobs = singleton
      { name = "foo";
        job =
          ''
            bla bla
          '';
      };

Eelco Dolstra 599015e8b0 * Split lib/default.nix into several files, as it had become a big
mess.  Also cleaned up some functions:

  - foldl appeared broken (it recursively called fold).
  - Renamed logicalAND/logicalOR to and/or.
  - Removed listOfListsToAttrs, eqStrings: obsolete.
  - Removed isInList, which does the same thing as elem.
  - stringToCharacters: don't return a "" at the end of the list.
  - Renamed concatList to concat, as concatList (singular) is a
    misnomer: it takes two lists.  Likewise, renamed mergeAttr to
    mergeAttrs.

  misc.nix still contains a lot of stuff that should be refactored and
  moved to other files.
