Subject: * First pass at collidable linksets * There will be bugs, you can
 count on that. To avoid them, set the linksets phantom * After region
 restart, the linksets restore in a non collidable state. * Linksets can but
 shouldn't be made physical with the physical checkbox or when you unlink
 them, they tend to explode. * After creating a linkset, you have to move the
 linkset or set it phantom and not phantom for it to become collidable. *
 There's a few ParentGroup references that need to be refactored.
