[pox-dev] CLI with POX

[William Emmanuel Yu]

Hi Murphy,

On the original unmodified code:

./pox.py py --help
>> ['py', '--disable', 'py', '--help']

./pox.py --help
>> ['py', '--disable', '--help']

On the modified code:

./pox.py py --help
>> ['py', '--help']

./pox.py --help
['--help']

The issue seems to be that py always comes up in the arguments list. 

On the last one runs properly. I am using the openflow VM. I just
updated the pox with betta.

Thanks.
