Allow selecting of GPUs

[sadreck]

Thanks for reporting it! I've just pushed a fix to the develop branch.

That's a great idea and I like the profile approach.

Thanks for the recommendation, I'll see what I can do.

I pushed this feature to the develop branch - if you have time give it a go and let me know if there are any issues. Profile creation is in the admin panel under "Device Profiles", and you will see a select box in the "Hashcat" session setup step. If a profile is deleted or disabled, the fallback will use all GPUs available (as it does now).

Don't forget to run the db migration for this, instructions at: https://github.com/ctxis/crackerjack/blob/master/docs/installation.md#update-to-latest-version (but checkout the develop instead of the master branch)

Heya, when you clone a fresh version of the develop branch and attemp to log in after creating an admin account, you get the following stack trace:

This is probably caused by the healthcheck assuming that the hashcat binary has been set, but it hasn't yet (the admin has to log on first and go to settings).

I've pushed this to master, let me know if there are any issues with it. Thanks.
