Put final touches on everything for demo on thursday (If we're using my
code. Of course I want to use my code). As of now, the login screen has
username/password and login/register. Login button works, starts login
actvity which recieves username and password. If username exists in
database, password is checked. If username does not exist, user is added
(this functionality will be moved to register activity after demo).
Enjoy!
