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)
