1st of a few sequencing changes

rename display_gamewindows() to init_sound_and_display_gamewindows()
(I know that's getting pretty long-named).

move activate_chosen_soundlib() into init_sound_and_display_gamewindows()
from moveloop_preamble().

Also included was a missing break in a switch related to sounds.
