Follow .cljs.edn file conventions #56
Description
boot-cljs encourages specifying options in .cljs.edn files.
When doing that using boot-cljs-repl involves manually reading these options and passing them on to start-repl. Not doing so can cause all kinds of breakage that can be hard to debug. Instead of boot-cljs-repl would follow this convention things would work out of the box.
