Fix #655: Async issues with threads outliving the chaiscript engine (#656)
* Fix #655: Join async threads before engine destruction to prevent heap-use-after-free

Issues #632 and #636 (PRs #651 and #653) both stem from the same root cause: async
threads spawned via async() can outlive the Dispatch_Engine, accessing shared state
(global objects map, type maps) after it has been destroyed. The fix moves async()
registration from the stdlib module into ChaiScript_Basic, where spawned threads are
tracked via Dispatch_Engine. The engine's destructor now joins all outstanding async
threads before destroying shared data structures.

* Address review: follow rule of 5, explicitly default move operations

Requested by @lefticus in PR #656 review.
