Made easier to add levels

[pro-nav]

Added ability to load the selected level

function createBoard() {
    loadlevel(1) //accepts integes and strings 
    for (let i = 0; i < layout.length; i++) {

• implement level selection along with difficulty Game Setting: Add Game Difficulty #70
• create more levels Add more levels!! #82

@RishabhDevbanshi can you assign some people to implement level selection UI?
Thank You!!

Hello, @pro-nav the difficulty stuff have been implemented #91 but I think we need a different screen for it so the gamer can select difficulty and choose levels.

@KhalebOBrien currently I am making new levels. I think #70 guys are implementing this difficulty screen so there is no need for separate level selection screen. I will check it out once I make some playable new levels.
