Coherency changes to special stage behaviour in anticipation of timeattack support

* Make everyone PF_NOCONTEST (but not explode) if the UFO/emerald reaches the end of its waypoint path.
    - Possibly temporary: Make the UFO/emerald go straight up at its final waypoint
* If you have PF_NOCONTEST, K_IsPlayerLosing is true
* If special stage in action and the only reason you'd be behind is your position, nobody loses
* Never eliminate last in special stage
* Time Over funny camera no longer occurs when PF_NOCONTEST but not dead
