Game crashes when snake fills up board

When you beat the game you get:

Uncaught TypeError: Cannot set property '-1' of undefined
    at SNAKE.Food.me.randomlyPlaceFood (snake.js:541)
    at SNAKE.Board.me.foodEaten (snake.js:981)
    at SNAKE.Snake.me.eatFood (snake.js:365)
    at SNAKE.Snake.me.go (snake.js:334)
    at snake.js:335

In the console, and the game freezes.

edit: The line numbers are off since I was making changes.

Thanks for the report! I'll try and put something in to catch this.

I can also add it. I'm making a few PRs right now.

@dginovker told me that I can take this one.

Sounds good

Just reproduced with small board size, snakeSpeed of 500 (the higher the slower, interesting...), and growthIncr of 1. I get the following (removed absolute path from .js filename for brevity):

TypeError: playingBoard.grid[row] is undefined snake.js:535:56
    randomlyPlaceFood js/snake.js:535
    foodEaten js/snake.js:989
    eatFood js/snake.js:357
    go js/snake.js:326
    go js/snake.js:327

Will look into it further.
