because I'm using reset(), not init()

I was waiting around 1 minute but speed didn't change much
but now I'm including precise speed (maybe I was waiting more than 1 min)

sorry but previously in cuda version blocks and threads wasn't set to
optimal numbers
I have no idea why on AMD real password cracking gives better speed

line 97k, and one hash is in file 'hash'

Use the "--show" option to display all of the cracked passwords reliably
