changed spdif default from "hw:0,2" to general alias "iec958"

based on a patch by Benedikt Hunz <hunz@hunz.org>
corrected typo in ugly spdif-warning message
added 32/20bit modes for 'high-end'-soundcards
disabled hw-mixer-access for big-endian machines
(mplayer seems to screw up hw-mixer on LinuxPPC running ALSA
needs more testing, but its safer to disable it for now.)
