#10 print the category of found entry in cddb-info.py

[Noam Yorav-Raphael]

Since cddb entry keys consist of a category+discid, it
is useful to know the category of the found entry. I
changed a line in cddb-info.py so that even if exactly
one match is found, the category and discid will be
printed.

I also converted tabs into spaces, since IDLE shouted
on me.

Thanks,
