WIP litable replacement.

We currently support loads of things the old litable wasn't able to do, including

• proper lexical vs dynamic binding
• lambda forms instrumentation
• proper setq/let instrumentation (following the sequence rules of elisp)
• macros are properly not instrumented (but I'm working on debug declaration parsing!)
• somehow sensible error handling (print error message instead of result after the function)
• automatic reinstrumentation = the "highlight" instrumentation is updated on-the-fly as you edit the function, no user input required
• we have tests now :)
