Auto update hashcat and possibility to use parameters

[fullbl]

Hi, I have added the code for building hashcat from a git submodule, so it should be always updated. Also, now you can pass parameters like --force.

Tested only on Linux, though :(

I'll see if I can find some time this weekend to test / review your contribution.
