Added local multiplayer MVP
SCOPE CREEP!!!
Added a menu to select single or multiplayer

Also the title and instructions
Reverse the positions of players 1 and 2

It is more intuitive for player 1 to be down in the right bottom
corner, because her controls are in the right bottom corner.
The player can escape to the menu at any time

Also, quit is disabled unless you are in the menu.
Added the "new challenger" state

A player can now join the game
Made the press return notice blink
Made the key controls more specific

Was getting bugs where players would react to eachother's keypresses
