Add bin/cue support. The following should work:

1) Basilisk and SheepShaver with sdl-audio and bincue on linux and os x
2) SheepShaver with bincue and core audio on os x

/* Geoffrey Brown 2010
* Includes ideas from dosbox src/dos/cdrom_image.cpp
*
* Limitations: 1) cue files must reference single bin file
* 2) only supports raw mode1 data and audio
* 3) no support for audio flags
* 4) requires SDL audio or OS X core audio
* 5) limited cue file keyword support
*
* Creating cue/bin files:
