Improve ASRangeController dealloc-safety.

Browse Source 
(1) We can't size nodes without a delegate, and if our owning controller
has been deallocated, our delegate will be nil.  Handle this more
gracefully.

(2) Our teardown code needs to be executed on the main thread, but it's
conceivable that we might hit refcount 0 on a background queue.  Force
deallocation to occur on the main thread.

Closes #27.
