/**
* Plays a sound definition file (*.sdf) through PC speaker. SDF files
* should reside in the gfiles dir. The only params passed to function are
* filename and false if playback is unabortable, true if it is abortable. If no
* extension then .SDF is appended. A full path to file may be specified to
* override gfiles dir. Format of file is:
*
* <freq> <duration in ms> [pause_delay in ms]
* 1000 1000 50
*
* Returns 1 if sucessful, else returns 0. The pause_delay is optional and
* is used to insert silences between tones.
