std -l wavto16

For converting 32-bits .wav to 16 bit. Audacity (at least my version,
1.3.12-beta) creates white noise at -72dB, and that's unacceptable.

wavto16 uses mplayer and works

Indefinitely better than Audacity, no noise generated now. That has to
be a bug in Audacity, so this is hopefully a temporary solution.

git-pa: Move the "git push" command to the end

I want it to push to the "Spread" (gitspread) remote first, if it
exists.
