Refactored Code and more functionality. Yay.

Added oop, an atlas powered unauth page, and now we have password
hashing.

HOWEVER, "Submission successful" was showing on submit.php. It was
susceptible to an injection so I secured it, and now "Submission
successful" won't show. There's some other issues but I've been looking
at this code too long now so I'm going to take a nice break.
