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
Move parameter handling into its own function and
better use the `.get()` function for dictionaries.
Early return on the failed checks is more readable.
The lambda function in the callback was long and
hard to read so moved it out.
