Make moving units unable to recieve new orders.

I need to fix it so units(that are your units) cannot be given new orders or make it so they can't be selected at all. They will be moving from one point to another point on the map and it would cause some problems if you could change the orders they have received by triggers.

To make them unselectable, you can use the trick I used when I made Glacial Wall, you could perhaps also let the units be selectable but cancel player orders using LastOrder.
