Moved the SCSI BIOS command handler to its own file (scsi_bios_command.c/h);

Removed all the SCSI BIOS ID/LUN swapping nonsense as it's no longer needed;
The makefile now knows the .h dependencies for everything in SOUND/;
Moved hdd*.* and scsi*.* to the HDD and SCSI subdirectories, respectively;
Fixed some leftover path name miscapitalizations in the makefile;
BT-542B is now BT-545C and BT-946C is now BT-958D again;
Implemented the last missing commands for the BT-958D;
MUNT and network are now optional at compile time but enabled by default;
When compiling the development branch, you now have to choose what of (Pro Audio Spectrum 16, Cirrus Logic, NVidia Riva) you want your binary to include.
