Region crossings redone: (1) removed WaitForCallback. Now that we are passing the entire agent with attachs in one big message we don't necessarily need to wait for confirmation. The callback sometimes is problematic and it adds delay to the process. (2) Z velocity sent to the viewer = 0. This is an heuristic; the Z velocity usually is negative, and it makes the viewer move the avie down. This only matters while the agent is in transit and therefore not being physically simulated by neither region. As soon as the receiving region receives CompleteMovement from the viewer, the position and velocity get corrected.
