WARNING: until now all disks was closed as multisession disks, this is
no longer the case, if the -m option isn't used disks are closed as
singlesession. The reason is that some drives wont close a disk
with one large image on in multisession mode, probably because it
"knows" that a new session wont fit on the media resonably.
Also update burncd with new stuff from various places that I've collected
and modified to my taste, its actually amasing how many thinks up the
same enhancements (none mentioned none forgotten):
Allow '-' to be used as filename for using stdin.
Add 'l' option to take a list of image files from 'filename'
