CL.py: adapted to newest version of CL library.
cdplayer.py: It is now also possible to give the CD's TOC as argument to init(). The TOC is a string consisting of 2 digits giving the number of tracks and then for each track the length of the track as number of minutes and number of seconds (2 digits each). cddb.py: Interface to the .cddb directory. Usage is the same as for cdplayer.py.
