Update utils.py to improve build_paq_cmd()

Update `utils.build_paq_cmd()` to convert all elements in the args list to their javascript counter-parts. This will recursively convert the keys and values of a dictionary until there are no more nested dictionaries and will also convert all the elements of a list as well.

Also made it so things like booleans, lists, and  dictionaries are not surrounded in quotation marks so they're treated like a normal javascript object. If that behavior needs changed. Please let me know
