Species and language datums, minor string removal.

To cut down on strings and make some breathing room:
- Commented out luchador strings.
- Commented out blob mode.
- Commented out wish granter.

Major purpose of this pull:
- Species and language data is now stored in datums.
- Add Language, Remove Language and Set Species have been added to VV.
- Life.dm has been generalized in regards to pressure and temperature to use species datum info.
- Icon generation has been generalized to use species datum info.
- I've tried to fix every instance of mutantrace I could find but I may have missed one or two. Mass testing is needed.
