The native sight is drawn at crosshair_angle outside aim mode too: one
masked condition in gunDrawSight (#ifdef PORT, beside the D373/D381
hooks) ignores GUNSIGHTREASON_NOTAIMING when the option is on; every
other reason and the MP menu still hide it. Default off is byte-identical
(frames 600/1200/1800); hipfire on/off differ only in the sprite region;
aim mode on/off identical. Findings D436.
