find-string-all

Finds all occurences of a string using find-string.

• (send a-wx:media-edit find-string-all str direction start end get-start case-sensitive) -> list of small integers
      str : string
      direction = 1 : small integer
      start = -1 : small integer
      end = -1 : small integer
      get-start = #t : boolean
      case-sensitive = #t : boolean

  The arguments are the same as for find-string.
