hashcat v0.50 hybrid rules

[mastercracker]

Would need the input from the devs since that I am not sure you are supposed to be able to use rules in the -a 1 mode for Hashcat. For Oclhashcat there is -j and -k that apply a single rule for the left and right side but for Hashcat that has only 1 wordlist, I am not sure what is happening with -r.
