Samuel Merritt 43ace3c628 Make RingBuilders deep-copy-able
We used to be able to deep-copy RingBuilder objects, but the addition
of debug logging (8d3b3b2) broke that since you can't deep-copy a
Python logger. This commit fixes that.

Swift doesn't really deep-copy RingBuilders anywhere, but third-party
code might.
