* modules/access/cdda.c: new MRL syntax: "[dev_path][@[title-start][-[title-end]]]".

  - if no title-start/end are specified, the whole cd is played.
  - if only a title-start is specified, only this title is played.
  - if a title-start and end are specified, this range is played.
  - "@title-start-" will play everything from the specified start position.
