Resolve "Refactor main menu with scene2d"
Changes in this merge request:
- All rendering code in MainMenuScreen has been alterned to use scene2d in the same way as is done for LoginScreen.
- MainMenuController has been altered to simply set the event listeners for each of the four buttons.
- Transitions to GameScreen, LeaderBoardScreen, and LoginScreen has been implemented.
- Changed the width and height fields in TankWarsGame to fit the menus' dimensions (landscape mode)
- The screen is now locked in landscape mode
- Some comments added and code clean-up done for LoginController and LoginScreen.
Closes #28 (closed)
