[WIP] Proof of concept Xref backend

[Gavinok]

Simple backend that basically just queries the REPL for the location of a given symbol. Works surprisingly well.

I still need to write a parser for (env) to gather keys to use with appropose but this does the bare minimum

This is very cool!! I don't get this to work either though. If I have a buffer with some code and do run-carp, should I just be able to put the point on a symbol and press M-. to go to the definition, or is there some more step?

[Gavinok]

@eriksvedang you would need to load the file into the repl (load "path/to/file") then since the :i will (usually) be able to give the location of the definition M-. should start working.

Here is a quick screencast of it in action

Hmm this doesn't seem to be as consistent as I had hoped. I am having trouble getting this to work seamlessly on base emacs. I'll try and improve the UX and ping you when I think it's ready
