Client Request - Change starting position on map

details:
If a player has no bases, set the x,y coordinates of the object with the lowest
id known as starting point.

motivation:
CoM players always start in the middle of nowhere as they have no base. Same
with players that intentionally have no base (like the NPC player in the
P4League games).

(this should be easy to implement I guess)

Cheers,
Jochen
