Code review comment for lp:~widelands-dev/widelands/bug-1811583-desync-with-territorial

Please pay attention for messages where each player get a different message (e.g. different land size). In think this is the case in territorial_time and territorial_lord. Using broadcast() will send the same message to all players.

We should also take care of the RST comments... i could do that if you don't want to touch them.
