Python3 Compatibility

[printfinn]

Dude, this is nice!
I used your code to complete my garage door remote control webapp.
While I met some little issues,

1. In Python 3, print is now a function, and followed by parenthesis ( ).
2. There seems to be some problem with the argument 'VERSION', I have to delete this parameter while calling the function.

After these two fixes, it works perfectly on Python 3.
Thanks so much for your code, after all!

Thanks for your feedback.

Python3 is supported now (in ver 0.7), and argument 'VERSION' is also supported.

argparse moved argument 'version' out from constructor. Just add it manually.

parser.add_argument('-v', '--version', action='version', version=VERSION)
