In lexer, prefer tokens to skipped separator characters

This was causing newlines in go and javascript to be parsed as
meaningless separator characters instead of statement terminators

Separate functions for building parse and lex tables
...
Now, instead of adding states to the lex table as they are needed
by the parse states, we iterate over the parse states after the fact
and set up their corresponding lex states. This has the nice side
effect that the lex states are in a more readable order.
