More rotatability (#4067)

* Make barstools, PA components, and radiation collectors rotatable.

Making barstools rotatable is so that people can spin on the barstool. (RP moment.)

The other two are more "functional" changes for assembling a PA.

* Allow rotating a rotate-while-anchored object if you're buckled to it.

Barstool spinny

* Fix bug with rotation of an object that someone is buckled to

* BuckleSystem: Efficiency improvements with directed events

* Don't need to unsubscribe anymore from events, so in BuckleSystem, just don't
