Signup

Implemented the Sign Up activity and integrated it in to the app. All the changes relating to the Login Activity came from connecting the two together. I tested it, and it runs fine (besides any gradle issues you may encounter). At the moment most of the "results" just toast since I cant start activities that dont exist yet.

What I mean is like, when the signup is successful, it should start the new house activity or whatever but we dont have that so it just toasts.

I will comment my code some day...
