"restart_rules_after_game_time" little fix

[TerminalHash]

Description

Fixes #2516

This change allows you to use the RestartAfterShortPostGame.as script without any problems and without subsequently rewriting the value of the “restart_rules_after_game_time” variable.

Steps to Test or Reproduce

Add next code into hook onRender in CTF_Interface.as for example:

		GUI::SetFont("hud");
		GUI::DrawText("Game time: " + getGameTime(), Vec2f(320, 20), SColor(255, 255, 255, 255));
		GUI::DrawText("Game time (CMap): " + getMap().getTimeSinceStart(), Vec2f(320, 35), SColor(255, 255, 255, 255));
		GUI::DrawText("Rules restart after game: " + this.get_s32("restart_rules_after_game"), Vec2f(320, 50), SColor(255, 255, 255, 255));
		GUI::DrawText("Rules restart after game time: " + this.get_s32("restart_rules_after_game_time"), Vec2f(320, 65), SColor(255, 255, 255, 255));

Merge changes from that pull request and you can check, what value is assigned to the variable “restart_rules_after_game_time” when using the RestartAfterShortPostGame.as or PostGameMapVotes.as script.

1. When you using RestartAfterShortPostGame.as, it's should be set to 300 ticks (by default);
2. If you're using PostGameMapVotes.as, it's should be set to 900 ticks;
3. If you run the tutorials, the restart time should be set to 150 ticks.
