This fixes warnings of -Wincomplete-patterns and -Wunused-imports in a few places. There are still warnings about using the deprecated type Control.Monad.Error which are not fixed in this PR.
-Wincomplete-patterns is mostly fixed by adding patterns like _ = error "reason why pattern is unreachable". -Wunused-imports is mostly fixed by just deleting the imports that it complained about. This included editing Version3/Parser/Lexer.x which is marked as being an auto-generated file, but it's checked in and I don't see what it was autogenerated from.
See #46.
