Added a comment about from where to start that application. 

If get_nth_partition/session_info() returns with anything else than a
B_ENTRY_NOT_FOUND, an error message is printed out.
The device name can now be specified on the command line, added shortcuts
to identify a particular device, i.e. "cd-1-slave" or "slave1-cd" or
"1-atapi-slave" would be expanded to /dev/disk/ide/atapi/1/slave/0/raw.
