Add docopt to requirements.txt

[Vinay Joseph]

Please add docopt to requirements.txt. When I tried to run

Vinays-MacBook-Pro:aioweb vinayjoseph$ python3 bin/aioweb-launch.py supplementme

I got the following error

Traceback (most recent call last):
  File "bin/aioweb-launch.py", line 19, in <module>
    from docopt import docopt
ImportError: No module named docopt
