LM hash support for OCLHC

[mastercracker]

I'd wish to see it.
It may not be bitsliced.
Ofc, it may not be possible to implement with current oclhc architecture(because of 7+7 password length limit).
Not top priority.

I am not sure that doing hybrid attack will really help things that much but since the finite keyspace is not that big, pure GPU bruteforcing is very efficient. With EGB, it takes less than 24 hours (2 GPUs) to bruteforce the whole 0-7 Upperalpha-Number-Symbol on 1 million hashes. OClhashcat can easily do that as well if the algorithm can be implemented.
