Added wordWrap()

wordWrap() will wrap the first x words in each image slide's caption.

Options available for count (# of words to wrap), wrapclass (CSS class
to give to the wrapped phrase) and restclass (CSS class to give to the
rest of the caption).

  wrapword: {
    count: 1,
    wrapclass: 'first-word',
    restclass: 'rest'
  }
