* use int to_bytes/from_bytes instead of struct
* fix ping queue bug and dht functional tests
* run functional tests on travis
* re-add contact comparison unit test
* dont need __ne__ if its just inverting __eq__ result
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
