Chrono Sphere designate-source animation should be displayed to allies.

The animation for the chrono sphere that shows where your units will be teleported from (before you click the destination and the magic happens) is only visible to the owner of the Chrono Sphere.

I had an argument with my team mate over this, when I was going to teleport his army to the enemy base - "Stop moving your units! Leave them where my chrono portal is" "what portal? what are you talking about?"

Ideally this should be controllable by the modder:
ChronoPortalVisibility=owner|friend|all
