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.
Add minor detail to recently added map description in doc/window.txt:
origin is in upper left and positive y goes downward, so not typical
Cartesian x,y coordinate plane.
Something that FIQ once pointed out: the fact that map column 0 is
not shown wasn't explicitly described anywhere. Add a paragraph for
NHW_MAP to doc/window.txt and describe it there.
(user-side decisions really, but as it stands right now
user-side decisions/options are made and processed by the core)
add a parameter to add_menu so color can be passed
