check class of topmost window to disable realtime counter

so keeping the game paused doesn't hurt your score, can maybe just check for subclasses of the persona screen

But maybe this ruins using our leaderboard for speedruns, unless speedrun mode disables this

No file or test is named. Start by locating the realtime counter and the topmost-window or Persona screen handling in the UnrealScript project, then reproduce the paused-game case and examine the leaderboard and speedrun-mode implications. Done means the counter behavior is defined for paused gameplay without undermining speedrun leaderboards.
