  Log Message:
  -----------
  Add 'void' values (using SNEK_NULL) and supress printing those.

This makes the top-level code skip printing values from functions
without a return value.

Also make snek_code_delete_prev non-inline as it's used more times.

  Log Message:
  -----------
  Clean up line number handling.

Make lexer track lex lines, including through unget.  Set snek_line =
snek_lex_line after each token is lexed.  Add op_line before each
statement line (compount-stat and simple-stat). This places one before
any executable code on a new line. Leave off an op_line after elif
because it doesn't fit on Arduino today.
