[gamecode] Generate the new opcode table
As I expect to be tweaking things for a while, it's part of the build process. This will make it a lot easier to adjust mnemonics and argument formats (tweaking the old table was a pain when conventions changed). It's not quite done as it still needs arg widths and types.
