Randy Heit ec17f5a5b9 - Undid some of the changes from lempar.c v1.30->v1.31, because it broke
error handling.
- Fixed: dehsupp/scanner.re defined "}" as the token RPAREN. dehsupp/parse.y
  also defined action_list_def as needing a RBARCE. I'm surprised it worked
  at all before. I guess Lemon really was too accepting.
- Changed the way that xlatcc handles include statements so that I don't need
  to modify the logic of lempar.c. I also discovered that the grammar was
  improperly defined and only accepted the first statement. It worked before
  because Lemon used to accept multiple times before reaching the EOF token.
  I have also verified that it is still generating the proper lumps.
- Removed some unused wadsrc files from the repository.
- Fixed my re2c upgrade.
- Updated lemon.c to v1.53.
