The client have to know it is now in turn 0 (==-4000) or in turn 84
(==375). If some code plan like "it will take 4 turns to reach the
position and 3 turns to construct a railroad and we started in turn 40
and have turn 46 the settler must be finished" it can assert that in
turn 46 the settler really is finished. If the settler is still
working there is a bug somewhere.

The current agent code store a plan like above to know what to do.

Yes the client can increase the turn every time it gets a new year
packet from the server. However how does the server knows the current
turn after a savegame is loaded and how will the server tell this the
client.

Situation:
 - turn n
 - server get turn done and performs turn transition
 - during this the server sends new unit info messages which indicate
 that the units have full move points
  - client thinks how cool I can still move this unit
  - however this trigger an assert since the unit gets to its goal
  before the plan
 - server sends (n+1)
