Save Player name when re-selecting level

[JNguyen96]

Currently, when the player selects a new level at the exit screen, the window for choosing 1 or 2 Players followed by the window for entering your name always appear. Change it so that the player only has to input their name once and then save it for following games until the program is exited.
