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).
