Do not show handshake files that are in cracked.txt with a key (match on filename) (#133)

Make cracked.txt a configurable variable
* Do not show handshake files that are in cracked.txt with a key (match on filename).
* Don't ask user for a crack-tool when attacking PMKIDs only
* Few minor cleanups

Fixed any_pmkid -> all_pmkid (to decide that we are strictly using hashcat)
* Added a safe-check to make sure we are indeed using hashcat for the PMKID hashes
* Changed the ugly split() to basename()

Making an FR from the TODO
