slideEnemy can now shoot at the player in a very dumb non-predictive manner every 2 second (ie no leading.)
Added bones for the highscores. Did a tiny bit of house keeping, comments and tidying.
Added the implementation of a high score. Only stores top 5 in a file called "highscores". Need to add a way for the user to imput their initials now.
Started tracking the new HighScoreEntry class and all other associated files that were forgotten from the last commit.
Removed unnecessary imports in GuiAppState to Map/Collection etc.
