New model to centralise password security.
Role column added, plus a little extra security so not just anyone can use this. Yeah, I know it's shitty, don't really care.
Updated registration page to use Hasher model.
Added bad/goodboxes, and standardised centered headers (h1-2)
Don't think we even need this, leaving it just in case.

Once logged in you redirect to home now anyway.
Was going to start working on cards, but then I decided to make users editable instead.
Yay, layout mostly done! Logic to come later, still being worked on.
