Local ip parsing shouldn't use ifconfig

[chadbrubaker]

As seen in #17 ifconfig output is platform dependent and we should find a more platform independent way to find all the ip addresses bound to interfaces.

[nikhilgeo]

Python netifaces package can be made used to find the IP address of the all the interfaces.

from netifaces import interfaces, ifaddresses, AF_INET
for ifaceName in interfaces():
addresses = [i['addr'] for i in ifaddresses(ifaceName).setdefault(AF_INET, [{'addr':'No IP addr'}] )]
print '%s: %s' % (ifaceName, ', '.join(addresses))

Can I work on this?
