WIP : better AST::debug_str()

Now its more contexually rich to the ast type, however I need to hookup tokens from parsing to the AST. There needs to be a way for the debug string to lookup the token and provide the contexual line.
Can either pass it ( TokArray* toks ) from the parser on failure (or `CodeFile`)..
Technically there is more than enough room for another Token* ptr. I could add another and specifiers would still have at minimum 14 slots before needing to extended to next specs.
**************... yeah
