Implementing first batch of unit testing (still WIP)
Also removed some unnecessary servlets (though the Home Servlet is still needed because of root path)
Finished 1st version of unit testing for Validator
Started Unit Test for UserBean
Finished unit testing for the UserBean. From now on, all new functionalities on the model or util layers should include unit tests. Unit tests for the controller layer still needs to be implemented.
