   Enable USE a52 aac mp4 x264 and xvid by default (acked by beandog).

aac/mp4 being the codec and container
xvid/x264 being the today's de facto video standards
flac being the de facto lossless codec
a52 being the sound codec for dvd's since USE dvd was already enabled by
default

so these make sense, basically just updated to todays standards

thanks, samuli
