Fixed bugs 1003, 1021, 1168 - fixed memory leak loading music

jjs@jjs.at 2011-03-11 11:37:57 PST
When using SDL_Mixer to play WAVE music, the call to Mix_FreeMusic does not
close the associated file handle.

There is a check in WAVStream_FreeSong() of wavestream.c like this:

if ( wave->freerw ) {
SDL_FreeRW(wave->rw);
}

But the variable freerw is not referenced anywhere else. SDL_FreeRW would also
not close the file from what I can tell.
