(fix re) Starting to re-write examples/04 (scheduling) for the direct JS API
(- fix) `stage()` now assumes `this`-context, have to bind it to `earth`
(- fix examples) Opted to directly modify responsibility

Libside, we have a #charge routine to do this ... but that seems like overkill in the JS API. It's
extremely simple to dive directly into the object-structure to do so.

Yeah, yeah, tight coupling, encapsulation, ask-don't-tell, &c ... whatevs. Fuck off.
(- fix) aliens weren't properly releasing ownership upon completion
(- re)
(- fix) Making sure examples/03 and 04 eventually exit. 04 also *works* now.
