MVP Design Pattern
Login page working
CSS style changes for easier viewing while testing.
Figured out how to center a panel perfectly on a web page window,
regardless of browser.
The login, lobby, and lobby room page guis are now encompassed by an
overall panel, for each respective place.
The lobby & lobby room views are now within an mvp style.
History management is beginning to be implemented: There are tokens for
"Login," "Lobby," and "LobbyRoom," allowing the user to use the back and
forward buttons on a web browser while inside of the application, to
return to a desired state
