setup.rb: use non-minified JS in development

[#58988346]
Makefile: copy non-minified js to vendor

[#58988346]

Run "make clean". Although I improved the Makefile a little bit the Makefile still doesn't recognize two important dependencies:

(1) public/vendor depends on certain non-minified js files in the vendor/ folder (so, Make doesn't copy the non-minified js over)

(2) public/embeddable.html and public/interactives.html depend on the contents of LAB_JS_DEPENDENCIES defined in script/setup.rb (Make doesn't know about LAB_JS_DEPENDENCIES so it doesn't know to rerun the haml step)
