12/21 modernizations from TG live (#103)

* sync (#3)

* shuttle auto call

* Merge /vore into /master (#39)

* progress

* Compile errors fixed

No idea if it's test worthy tho as conflicts with race overhaul and
narky removal.

* Update admins.txt

* efforts continue

Fuck grab code, seriously

* grab code is cancer

* Execute the Narkism

Do not hesitate.

Show no mercy.

* holy shit grab code is awful

* have I bitched about grab code

My bitching, let me show you it

* código de agarre es una mierda

No really it is

* yeah I don't even know anymore.

* Lolnope. Fuck grab code

* I'm not even sure what to fix anymore

* Self eating is not an acceptable fate

* Taste the void, son.

* My code doesn't pass it's own sanity check.

Maybe it's a sign of things to come.

* uncommented and notes

* It Works and I Don't Know Why (#38)

* shuttle auto call

* it works and I don't know why

* Subsystem 12/21

Most Recent TG subsystem folder

* globalvars 12/21

Tossed out the flavor_misc and parallax files

* Onclick 12/21

as well as .dme updates

* _defines 12/21

ommited old _MC.dm

* _HELPERS 12/21

Preserved snowflake placement of furry sprites

* _defeines/genetics

reapplied narkism holdover for snowflake races.

* Oops forgot mutant colors

* modules porting 12/21 + Sounds/icons

Admin, Client and most of mob life files ommitted

* enviroment file

* Admin optimizations

ahelp log system kept

* Mob ports 12/21

Flavor text preserved

* datums ported 12/21

* Game ported 12/21

* batch of duplicate fixes/dogborg work

Dogborgs need to be modernized to refractored borg standards.

* moar fixes

* Maps and futher compile fixes
