Vorbis dev - Mar 2001 - patch to add device-option to ogg123 rc file

Below is a patch for vorbis-tools-1.0beta4 ogg123.

It adds support for using the rc file (like /etc/ogg123.rc) for
configuring the device-options. In addition, comments can be used (when
they start a line).

My ~/.ogg123rc:
default_device=oss
default_options=dsp:/dev/audio

Please share your comments.
