Prevent mouse from influencing player cam in Combat Sim pause menu

[ZenithMDC]

Moving the mouse in the Combat Simulator pause menu caused the player camera to snap to a new location after leaving it. This was due to the relative mouse delta not being reset when leaving the menu. But I wondered: why did this not occur during a non-Combat Sim pause? I created a couple of input frame log files to figure that out:

// MPPAUSE

Hit mpPause
g_PlayersWithControl: false
inputAutoLockMouse(false);

// NORMALPAUSE

So, because a normal pause has 25 input frames of latency between the huge delta (aka the next call to SDL_GetRelativeMouseState()) and player control becoming true again, the camera snap is avoided without intervention.

Anyway, I hope my solution is okay. If not, let me know.
