* Still not "print" option for --crack.
* Checks hashcat for devices, uses --force if no devices are found.
* Interrupting --crack stops entire process, not just a single crack attempt
* Changed wordlist location, hopefully completes #102.
Process.__del__() swallows AttributeErrors now (for #120).
And hashcat won't output the key if it's already been cracked (it's in the pot file).
So we run hashcat again, with the --show parameter. This does not try to crack again.
