Better heuristic to attack targets more efficiently

[derv82]

Currently wifite tries all selected targets in-order, trying WPS pixie-dust, then the PIN attack, then WPA handshake capture.

Ideally the script would:

1. Target closest APs first
2. Target WEP networks first
3. Target WPS networks with Pixie Dust
4. WPA: Capture handshake, try small/medium sized word lists
5. Try WPS PIN attack

This way the most-vulnerablr targets are attacked first.

Ideally we would run multiple attacks against targets on the same channel/frequency, but this might screw up some things (eg deauthing multiple clients at the same time, reaver getting confused, etc).

a simple first step might be to only show targets with clients, I would appreciate a flag like that

Thanks for creating #79 to track this.
