TrophyRace: Show current racing time at top

The rottags key alone now toggles hog tags; preecise+rottags is used to cycle tags I figured that the toggling hog tags on and off is a bit more important than changing the tag types, because you sometimes run into a hog whose tags block your view, so a 1-key press is helpful. On the other hand, you probably only want to changing the tag types in the game once (if at all).
