  Tutorial S2: Warn about orcs crossing the river when they cross

Closes issue 2a of #1584

Previously the warning was always given on turn 7. It will still trigger even
if the player has units ready to defend that crossing, because I think it's
better to show the message and let the player think "I'm already ready" than to
have it pop up once some fighting has already happened; and it seems easier to
test this logic than to test logic for not showing the message if the crossing
is currently guarded.

Also add a first_time_only=no to the check_income event, so that it can trigger
on turn 7 if it doesn't trigger on turn 6.
