Setup.py integration

Semi-major version bump for significant changes:

1. Wifite can be installed using setup.py (sudo python setup.py install)
   • This installs wifite as a python module to the machine.
   • Includes an executable script in/usr/sbin/wifite
2. The base script ./Wifte.py was moved to bin/wifite
   • But this script can't be executed via python bin/wifite unless wifite is installed.

To run wifite:

1. If installed, just type sudo wifite at any terminal
   • wifite should be found in the current path as it's installed to /usr/sbin
2. If not installed (e.g. git cloned), type sudo python -m wifite in the clone repo directory.
