Implement models and basic login/registration

- UserProfile, Sports, Events, Courts **models added**.  
  - UserProfile is in `accounts.model` and only has contains the optional phone-number field and the self incrementing reputation point field
  - Events, Sports and Courts is in `events.model`

- Implemented **basic registration** via email + password + username.  Login + Logout. 
  - In views, use `request.user.is_authenticated()` to check if user is logged in.
  - Access the admin page `localhost:8000/admin` 

- Added **script to add to database** users, sports, courts, and events
  - Make sure you can run it by executing in terminal  
`pip install django-extensions`  
`./manage runscript addDB`  

- Still **needz FaceBook login integration**, but this will get the ball rolling on other features.  oAuth is a new concept for me and I do not feel I have enough time to read through the docs within the timespan we have left for this project.
