Fix critical failure to cleanup teams list after rejoining game after a force-quit. Fixes bug #597

Backed out changeset 6c0cf6b9eff8. Scripters should be prepared for nil and pretending the gear exists would cause more pain

Clean up more visual gears stuff in scripts - Make vgears non-critical if possible - Add nil checks where needed - Fix related bugs - Remove doomed attempts to call FollowGear on vgears

Clean up legacy visual gear stuff in ClimbHome, fix star despawn, make stars non-critical

Remove calls to GetVisualGearValues where it's not needed

Animate: Remove follow arg from AnimVisualGear

use 0s instead of nils to try to protect script assumptions
