instead of recursive bytes2unicode use a proper JSONEncoder to conver bytes->unicode for json.dumps() removing excessive isinstance(data, bytes) checks py3: / -> // and list() around .items() that gets modified in loop moved lbrynet.undecorated to where its actually used and hopefully we can delete it eventually removed build/upload_assets.py, travis can do all this now
