Babashka support!

Tracing and replay of re-frame handlers and subscriptions, as well as other similar function registration operations

Tracing of anonymous functions

Tracing of loop/recur blocks

Ability to extend Playback’s optypes in order to trace/replay similar custom macros

A new defn was being created on every replay due to the usage of gensym, thus increasingly polluting the namespace until the next reload. Function generation now uses a hardcoded suffix with extra-paranoid checks to eliminate the very minimal chance of overwriting an existing var (if you happen to be naming your functions some-fn__playback_core__, Playback will let you know.)

Removed dependency on ClojureScript in Clojure-only projects due to the possibility of dependency conflicts (h/t @Cyrik)

Extracted build/deployment code into gnl/build.simple

Added spec validation for the minimal API

Cleaned up a lot of messy, late-night, "how is this even working" kinda code
