Merge pull request #126 from itpun/master

Added new admin landing page and fixed button variable names
Course access first version, grade access skeleton
Created GUI Driver

- Once the Login Screen is tweaked a bit, (next commit) our app will run!
Removed `LoginScreen.java`'s main()

- It is now called from the MarkSharkGUI driver class.
- Our app runs!
Reformatted LoginScreen.java

- This file can never be edited through netbeans again, or the contents
  of `initComponents()` will be altered again, destroying all the new changes.
Login screen is closer to being able to transition to landing page

- The user will also now be shown a prompt if the password they
  entered is too short.
Tweaked database classes based on new tables

Updated the database classes that already had work done to comply
with the new table formats. These classes are unfinished, but provide
functionality for accounts and internal aspects of courses.
Added various user interfaces
