This makes 'dancing' impossible with patrol, for both single units and

It further makes the formation and regular patrol code more similar.
The diff harcodes an integer wait time as it relies on timer calls
instead of range queries, as that was much simpler to implement.
Animations for the waypoint-waiting is also unimplemented.
