Gifts

It is now possible to give gifts to your allies without receiving anything in return. This enhancement also provided the opportunity to refactor some of the trade code, encapsulating it within the Order object, and get it out of the GameServer (where it really did not belong).

We also had our first simulation stopper - neutral pop centers are not controlled by players, thus they cannot be checked to see if the noble usurping it is an enemy. A very obvious oversight - this is why we have a testing phase.
