Implementing Harpoonable Settings in the Player Select Screen

Implemented the settings in the player select area and finding that some like Co-op have to toggle the others!

I already got tired of the menu buttons from earlier so I'm glad they're gone now. Later, I might have to squish down this screen to fit better on 1920x1080 - a downside of working on a 1920x1200 screen. At that point, I may simplify the junkyard piles on the edges. One plus of this system is that it also is a solution for having some harpoonable objects on this screen, and I'm considering if they should be draggable into the play area.
