Rearranged the code a bit, breaking walk.cc into several different files:

  compare         compare_items<T>
  handler         item_handler<T>
  iterators       used to iterators sets of journal objects
  filters         derived from item_handler, they morph the result set
  output          derived from item_handler, these do the printing

Also, created a new 'help' files which contains just Ledger's help text.
