Curly brace support

[chatterine]

In earlier versions of xkas (namely v6), curly braces {} can be used to organize your code better. They're ignored by the assembler and don't really do anything other than prettifying the code. Is this feasible to be done on xkas-plus? At the moment it's spitting out errors if I try to use them. Correct me if I'm wrong, but aren't curlies currently used in xkas-plus for something else (labels, it seems)? It might be nice if curlies are able to be used for code organization like in older versions of xkas, but I understand if that's not something that's able to be done.
