Fix problems with vertical look in Heretic #428

Fixes bk_look_center not working properly while recording a demo
Fixes #427
Fixes the problem when the slightest vertical movement of the mouse doesn't affect vertical look. Hanomamoru complained about this on his streams. I found the same problem with horizontal mouse movement to the left while recording a demo, but couldn't track down the source.

I don't think those changes can break demo compatibility, but testing is required. @JNechaevsky

Applied recommendations from fabiangreffrath/crispy-doom/pull/1007

I also decided to not apply dead zone fix in demorecording mode because it makes vertical mouse look more sensitive than horizontal mouse look. However, in demorecording mode horizontal mouse look has dead zone only then turning left, turning right has no dead zone. In Crispy Heretic, dead zones are present on both sides in demorecording mode.
