Brian Picciano 4870455430 Completely refactor gg with new BNF file and decoder
The new gg format is based on a BNF file which can be found in the `gg`
directory. The code for decoding `.gg` files has been refactored to
mirror that file. The result is more resilient parsing, better errors,
and a greater ability to extend the format in the future.

The new decoder is notable in that it does not use a lexer. Both lexing
and parsing are done in a single step.

The format syntax itself has also been modified. Rather than using
semi-colons everywhere, commas are used as separators in tuples.
Additionally the final comma/semi-colon is no longer required.
