2.1.9: --pmkid option, cleaned up --cracked, other bug fixes.

PMKID:

* `--pmkid` option only attacks WPA networks with PMKID capture + crack
* Decreased PMKID capture time from 60 seconds to 15 seconds.
* Ignores PMKID attack if `--wps-only` is set.

WPS:

* Ctrl+C while waiting for `bully` to fetch PSK = remembers PIN, PSK is unknown.

Misc:

* `--cracked` prints results on single lines (much easier to read)
* Fixed typo when required dependencies are not found (closes #127)
