DNA2 EPISODE 2: Revenge of the Bugs

Made after DNA2 hit /vg/'s main server after no one tested anything.

* Gene activation/deactivation made modular, refactors domutcheck.
* Standardized genetics disks and injectors a bit in response to buffer corruption issues. (Untested)
* Lots of major bug fixes.
* Skin tones fixed.

Still needs further testing. All I did was mess around with monkeys.

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.

Missed the gene Life() call.
Fix earlier screwed commit
And now tested in game, with some fixes.
DNA2 rangebug, if any hair/beard/eye RGB values are 0 it won't encode it into the dna.

This is a hacky fix and is temporary until I can sit down and figure out exactly why it's not encoding that block of DNA properly.

The result of it not encoding it into the dna is that if you clone the person they have a random value there that was assigned at round start.
