doom: fix glitchy mouse movement
- fix stuttering mouse movement by using all mouse deltas during a tic, not
just the last one (G_Responder can be called more than once per tic)
- change mouse filtering and sensitivity calculation: divide mouse delta by
half, casting to double, and only then multiply by sensitivity
10 * Δ * (sens+5) / 10 → Δ * 0.5 * sens
with sens in [1;10]
