* 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.
