Games with "-autostart-nonvisual" do not end nor generate a replay.

[gentz]

Games started with "-autostart-nonvisual" never end. They also never generate a replay.

Tested with the following command with a22 for 72 thousand turns:

0ad \
	-mod=public \
	-autostart="$MapDir" \
	-autostart-nonvisual \
	-autostart-seed=-1 \
	-autostart-size=192 \
	-autostart-players=2 \
	-autostart-aiseed=-1 \
	-autostart-ai=1:petra \
	-autostart-ai=2:petra \
	-autostart-aidiff=1:5 \
	-autostart-aidiff=2:5 \

Testing with the following command on r21096 for 50 thousand turns.

binaries/system/pyrogenesis \
	-mod=public \
	-autostart="$MapDir" \
	-autostart-nonvisual \
	-autostart-seed=-1 \
	-autostart-size=192 \
	-autostart-players=2 \
	-autostart-aiseed=-1 \
	-autostart-ai=1:petra \
	-autostart-ai=2:petra \
	-autostart-aidiff=1:5 \
	-autostart-aidiff=2:5 \

Edit: MapDir is "random/mainland". I've just tested with ai two with difficulty 0 and the game still isnt ending.
