Rewrote the implementation of the SwapEndian_16() and SwapEndian_32() functions so that they compile down in most instances to minimal loads and stores rather than complicated shifts.
Fixed SCSI.c implementations of all the demos/projects casting the block count to a 32-bit temporary before calling SwapEndian_16().
