First efforts to add sound/music to the main menu.  The big clip class
that is here now is not mine, but I'm trying to see if I can make use of
it.  Right now I have a starting place for making sounds in char select
and battleground select.  You guys can use my Simple Sound_Playback
class to make sounds in the battle screen.  Must be 16 bit uncompressed
wav files though.  Still need to iron out some problems in char select,
but it's all looking good.
