updates to XMonad.Prompt re: word-oriented commands

  + change killWord and moveWord to have emacs-like behavior: first move
    past/kill consecutive whitespace, then move past/kill consecutive
    non-whitespace.

  + create variants killWord' and moveWord' which take a predicate
    specifying non-word characters.

  + create variants defaultXPKeymap' and emacsLikeXPKeymap' which take
    the same sort of predicate, which is applied to all keybindings with
    word-oriented commands.
