by rabande[sto10-tsk25] Add authentication page for registered users
The "login.xhtml" page has been created that allows the registered users
to be login and logout. The "loginController.java" controller has been
created to support the "login.xhtml" page. The "header.xhtml" page has
been modified so that login users can be logout.
