Massive overhaul

overhauled system to allow for users to login to system. Standard login
interface, no user information stored now (except for username &
password [means no password recovery at this time]). No support for
administrators... nor a way to add people to the database without
entering the information manually at this time. Login stolen from
(http://net.tutsplus.com/articles/news/how-to-build-a-login-system-for-a-simple-website/).
The login uses md5 (yes I know its terrible, i don't care [security not
an issue at this time]).
