Redesigned the bracket view for 4 and 16 players. Added som visual feedback for when players are added. Refactored controllers to use the static fields instead of duplicating code.

Fixed the main menu view. Refactored the MatchController to use the static changeScene() method. Javadoc, and minor changes to the table-tennis-view

Refactored the changeScene() method in TableTennisApplication to be static. Used the static method in TournamentController instead of making new instances every time.

Implemented the 8 and 32 player bracket, tested the load function and it seems to work. A redesign of the bracket view would be advised
