[Freeciv-Dev] (PR#12949) Players can use the AI moves twice bug too.

Players can use the same trick that the AI was taught not to do:

- empty city by attacking with a frigate
- Wait until all other players hit end turn, or there are few seconds left
- Unload warrior
- hit end turn
- capture city in second move in sequence

This problem could be cured by making turns overlap, i.e. with 8
players and 40 seconds time, schedule the end turns of players to be 5
seconds apart.

Just an idea ;-)
The code forcing the AI to go slow then would be less necessary.

There are basic problems with this idea, such as 
- what happens if players hit end turn and don't use the full time
- this would make wars between players that are 20 seconds apart be
different from those 5 seconds apart.

But maybe this could be worked out?

The other way would be to have freeciv work more like an RTS, for
example by attaching an activity points/ last move time field to each
unit, but that would be unwieldly I guess.
