Added Admin Login. Currently it's identical to user login except it's called admin.
I think this is the actual admin login. The last commit had minor changes
Made the "guest" user now a real user with name "Guest[IPaddress]". System checks if a guest of that IP address exists and creates one if it doesn't. The guest user never is signed in. Currently, the guest users show up in the all user page, but that will change. Functionally, the votes and comments are the same except that the guests can't comment (that can change if need be).
