Move giant lookup table into another translation unit

Also, rewrote it as a constant variable instead of a function
that imperatively fills a map. It's shorter, faster the compile,
and (depending on how badly the compiler screws it up) maybe
faster to run.

And, of course, it starts breaking up that giant .cpp file.
