pt3: init zeroed vars with loop
...
switching songs, sometimes they'd start wrong due to vars not
being initialized. Easier to just zero everything than try to
figure out which field we weren't getting. Also makes code smaller.

fixed a few minor bugs here from qkumba's version as it was
making the validation tests fail. One was not zeroing out
mixer/envelope, and one was not saving some values properly
