WPA/WPA2 support

This script connects the AR Drone to a WPA/WPA2 secured network.

Usage:
     script/connect "<essid>" -p "<password>" [-a <address>] [-d <droneip>]
     Note that order of arguments matters.

  <essid>
          Name of the WPA2 network to connect the drone to.

  <password>
          Password of the network.

  <address>
          (optional)  Address to  be set  on the  drone when  connected to  the
          network. Use  a different address  than the router's default.  Set to
          "auto" (default) to let the router DHCP server auto-assign an IP.

  <droneip>
          (optional) Current drone's ip address. Default is 192.168.1.1
