DNA2 Bug Fixes - Part 2 (CHERRY PICK)

We discovered that most of the problems were were having was because of BYOND passing lists (e.g. SE and UI) by-ref instead of the assumed by-val.

This commit adds dna.Clone() and (UI|SE).Copy() where needed.  These should be used where DNA or SE/UI lists are COPIED, otherwise changes made in the reference will affect the real strand.

This change also messes with the gene activation logic.
